Detailed Description

Description:

This is the base class from which materials and textures are subclassed. Methods are provided to access the name, flags, and sub-materials/maps. There is also a method that is called when the material or texture is to be displayed in the material editor parameters area.

Note the following about dialog proc processing of sub-map buttons:

When you post the message:

PostMessage(hwmedit, WM_TEXMAP_BUTTON, i,(LPARAM)theMtl);

You are telling the system that the user clicked on the button for the 'i-th' sub-map of theMtl. The message doesn't propagate up – it goes directly to the materials editor. It then uses calls on theMtl->SetSubTexmap() and theMtl->GetSubTexmap() to assign the new map. So even if your material has some complicated internal hierarchical structure of references, to the system it is still a simple "logical" hierarchy of a material with some sub-texmaps.

Data Members:

Quat meditRotate;

This data member is available in release 2.0 and later only.

This describes the rotation of the sample geometry in the materials editor.

ULONG gbufID;

This is the G-Buffer ID of the material or texmap. This is a "effects number" assigned in the materials editor to a map or material, and it will be written into the effects channel of the G-Buffer when a pixel with that material on it is rendered. To implement this, each map or material, in the beginning of its Shade(), EvalColor(), or EvalMono() methods should have the code:

if (gbufID) sc.SetGBufferID(gbufID);

__declspec()

__declspec ( deprecated  )

inline

Note

This method has been deprecated in terms of implementation as of 3ds Max 2022. Plugin developers should implement GetFullName(bool localized) instead. This method can no longer be overriden and calls to it are now forwarded to the function that replaced it with a "bool localized" value of true. This is done so that plugin developers who do not localize their plugins don't have to update all the places where they call this method. Plugin developers who do localize their plugins should analyze the places where they call this method to decide what value to pass it for the "bool localized" parameter.

See also

MtlBase::GetFullName(bool localized)

            {
                return GetFullName(true);
            }

GetFullName()

virtual CoreExport MSTR GetFullName ( bool  localized )

virtual

Remarks

Implemented by the System.

This method returns the name that appears in the track view. It returns the "Instance Name(class Name)". For example "Green Glass (Standard)". The default implementation should be used.

Parameters

localized

If true, then the name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the name in English.

Reimplemented in MSPluginTexmap, and MSPluginMtl.

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

{ return 1; }

Requirements()

virtual CoreExport ULONG Requirements ( int  subMtlNum )

virtual

Remarks

This method returns the cumulative requirements of the material and its sub-materials and maps. The default implementation just ORs together the local requirements of the material with the requirements of all its children. Most materials will only need to implement LocalRequirements().

Parameters

subMtlNum

Specifies the number of the sub-material whose requirements should be returned. -1 may be used to return a value generated by looping over all the sub-materials and ORing together the requirements.

Returns

See Material Requirements Flags.

Default Implementation:

The default implementation automatically traverses the sub-material/map tree. On any MtlBase that returns TRUE for IsMultiMtl() it will only recursively call the sub material (or map) for the subMtlNum called. The exception to this is when subMtlNum<0: in this case all sub-mtls and submaps are enumerated. Therefore the LocalRequirements() method below only needs to consider the material or map itself, not the sub-mtls and sub-maps.

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

LocalRequirements()

virtual ULONG LocalRequirements ( int  subMtlNum )

inlinevirtual

Remarks

Specifies various requirements for this material. The value returned from this method should not include requirements of its sub-materials and sub-maps.

Parameters

subMtlNum

Specifies the number of the sub-material whose requirements should be returned.

Returns

See Material Requirements Flags.

Default Implementation:

{ return 0; }

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

{ return 0; } 

MappingsRequired()

virtual CoreExport void MappingsRequired ( int  subMtlNum, BitArray &  mapreq, BitArray &  bumpreq  )

virtual

Remarks

This method gives the UVW channel requirements of the material and its tree. The default implementation just OR's together the local mapping requirements of the material with the requirements of all its children. For most materials, all they need to implement is the LocalMappingsRequired() method.

Parameters

subMtlNum	Specifies the number of the sub-material whose mapping information is retrieved.
mapreq	This array of bits is initialized to an empty set with MAX_MESHMAPS elements. Each bit corresponds to a mapping channel. Set a bit to one to indicate the material requires the corresponding UVW channel.
bumpreq	This array of bits is initialized to an empty set with MAX_MESHMAPS elements. Each bit corresponds to a mapping channel. Set a bit to one to indicate the material requires the corresponding bump mapping channel.

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

LocalMappingsRequired()

virtual void LocalMappingsRequired ( int  subMtlNum, BitArray &  mapreq, BitArray &  bumpreq  )

inlinevirtual

Remarks

This method specifies UVW channel requirements for the material: This method should not include UVW channel requirements of any sub-materials and sub-maps.

Parameters

subMtlNum	Specifies the number of the sub-material whose mapping information is retrieved.
mapreq	This array of bits is initialized to an empty set with MAX_MESHMAPS elements. Each bit corresponds to a mapping channel. Set a bit to one to indicate the material requires the corresponding UVW channel.
bumpreq	This array of bits is initialized to an empty set with MAX_MESHMAPS elements. Each bit corresponds to a mapping channel. Set a bit to one to indicate the material requires the corresponding bump mapping channel.

Default Implementation:

{}

Sample Code:

All 2D textures that use UVGen or otherwise select mapping channels need to implement this method Here's an example:

void LocalMappingsRequired(int subMtlNum, BitArray & mapreq, BitArray &bumpreq)
{
    uvGen->MappingsRequired(subMtlNum,mapreq,bumpreq);
}

All 3D textures that use the XYZGen to put up a coordinates rollup must implement this method. Here's an example:

void LocalMappingsRequired(int subMtlNum, BitArray & mapreq,BitArray &bumpreq)
{
    xyzGen->MappingsRequired(subMtlNum,mapreq,bumpreq);
}

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

{  }

IsMultiMtl()

virtual BOOL IsMultiMtl ( )

inlinevirtual

Remarks

This method returns TRUE for materials or textures that select sub-materials based on submaterial number (for example a mesh faceMtlIndex).

The only materials for which this method should return TRUE are those that choose to use one of their sub-maps or sub-mtls based on the submaterial number. For the majority of materials and maps, they should return FALSE, and in that case all of the submaterials and maps are enumerated by MtlBase::Requirements().

Default Implementation:

{ return FALSE; }

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

{ return FALSE; }

MapSlotType()

virtual int MapSlotType ( int  i )

inlinevirtual

Remarks

This method returns TRUE for materials or textures that select sub-materials based on submaterial number (for example a mesh faceMtlIndex).

The only materials for which this method should return TRUE are those that choose to use one of their sub-maps or sub-mtls based on the submaterial number. For the majority of materials and maps, they should return FALSE, and in that case all of the submaterials and maps are enumerated by MtlBase::Requirements().

Default Implementation:

{ return FALSE; }

Implements ISubMap.

Reimplemented in Texmap.

{ return defaultSlotType; }

DeactivateMapsInTree()

CoreExport void DeactivateMapsInTree

(

)

Remarks

Implemented by the System.

This method must be called on a sub-material or sub-map when it is removed, in case it or any of its sub-maps are active in the viewport.

Update() [1/2]

virtual void Update ( TimeValue  t, Interval &  valid  )

pure virtual

Remarks

A material has a Shade() method, and a texture map has a EvalColor() method. These are called by the renderer for every pixel. This method is called before rendering begins to allow the plug-in to evaluate anything prior to the render so it can store this information. In this way this information does not need to be calculated over and over for every pixel when Shade() or EvalColor() is called. This allows texture and material evaluation to be more efficient. It is generally called once at the start of each frame, or during interactive playback when the time changes. It is not guaranteed to get called on every frame, because if you returned a validity interval that covers several frames, your parent material won't bother to call you if the current frame is still in that interval.

Parameters

t	The current time.
valid	The validity interval to update to reflect the validity interval of the material or texture at the time passed.

Implemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

Update() [2/2]

void Update ( TimeValue  t, Interval &&  valid = FOREVER  )

inline

Remarks

Use this override when validity interval is irrelevant

{ Update(t, valid); }

Reset()

virtual void Reset ( )

pure virtual

Remarks

This method is called to reset the material or texmap back to its default values. This should be done by calling the Reset method of the material or texture map plugin's class descriptor (ClassDesc2::Reset). In addition, the plugin can execute any other initialization code it has. Example from maxsdk\samples\materials\dblsided.cpp

void DoubleSided::Reset() {
    dblsidedCD.Reset(this, TRUE); // Resets all pb2's
    Init();
} 

Note

When migrating plugins from ClassDesc to ClassDesc2 and IParamBlock2, do not forget to update this method to call the class descriptor's Reset method. If the plugin's Reset tries to replace parameter block objects based on IParamBlock2 that use the P_AUTO_UI flag, the UI code will continue to hold a pointer to the replaced parameter block, and this will lead to problems.

Implemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

Validity()

virtual Interval Validity ( TimeValue  t )

pure virtual

Remarks

This method is called to determine the validity interval of the material or texture.

Parameters

t	Specifies the time about which to compute the validity interval.

Returns

The validity interval of the item at the specified time.

Implemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

CreateParamDlg()

virtual ParamDlg * CreateParamDlg ( HWND  hwMtlEdit, IMtlParams *  imp  )

pure virtual

Remarks

This method gets called when the material or texture is to be displayed in the material editor parameters area. The plug-in should allocate a new instance of a class derived from ParamDlg to manage the user interface.

Note: The following is a discussion of this CreateParamDlg() method, and the SetDlgThing() method, and the way they relate to the ParamMap2 system. A good example for this discussion is a texture map which typically has several rollouts, say its texmap parameters, a UVW coordinates rollout, and an Output rollout.

The normal way for a texmap to implement these other (common) rollouts is for the it to create a UVGen instance and a TextureOutput instance as 'sub-objects' in the map and then ask them to put up their rollouts when it is asked to do so by the Materials Editor (in CreateParamDlg()). The Materials Editor requires a ParamDlg pointer back from the CreateParamDlg() on which it calls methods to control the UI, such as time change updates or loading up a new texmap of the same class into the UI when the user switches them, so that the whole UI doesn't need to be rebuilt.

Prior to the ParamMap2 system, a texmap would implement its own ParamDlg subclass and would keep track of the UVGen and TextureOutput ParamDialogs and pass on any time change or SetThing() calls to them. ParamMap2 introduced its own ParamDlg subclass (Class IAutoMParamDlg) that you can ask it to build for you and have manage all interaction with the Materials Editor automatically. As before, this still needs to know about the other (sub-object) ParamDlgs, and so it has the ability to keep a list of 'secondary' ParamDlgs to which it passes on the SetTime()s and SetThing()s.

When the Materials Editor asks the texmap to CreateParamDlg(), the texmap asks its ClassDesc2 to build one of these (ClassDesc2::CreateParamDlgs()). If the texmap itself has multiple ParamBlock2s, CreateParamDlgs() builds one ParamDlg per pblock/rollout, makes the first of them a 'driver' and adds the rest as secondary ParamDlgs. The texmap then asks the UVGen and TextureOutput objects to CreateParamDlg() for their rollouts and adds them to the driver IAutoMParamDlg also.

Now consider the need for the SetDlgThing() method below. It is related to the SetThing() method that the Materials Editor calls on the 'driver' ParamDlg to switch into the UI a texmap of the same class as that currently in the UI. Normally, the driver IAutoParamDlg would propagate the SetThing() to its registered secondary ParamDlgs. In the case of multiple paramblock2s in the texmap, this would be correct, since the 'thing' in this case is the incoming texmap. But this doesn't work for the secondary UVGen and TextureOutput ParamDlgs; their 'things' are the UVGen and TextureOutput subobjects of the incoming map. So, IAutoParamDlg first calls SetDlgThing() on the incoming texmap so that it gets a chance to call the correct SetThing()s on the sub-object ParamDlgs with the appropriate incoming sub-objects. A clear example of this is in Gradient::SetDlgThing() in /MAXSDK/SAMPLES/MATERIALS/GRADIENT.CPP. It is called once for each secondary ParamDlg. For those ParamDlgs that have special SetThing() requirements, it does the appropriate sub-object SetThing() and returns TRUE. If it does no special handling for a particular ParamDlg, it returns FALSE, signalling to the IAutoMParamDlg that it should do the standard SetThing() propagation for that dialog.

The Render Effects dialog has a similar arrangement to the Materials Editor for controlling Effect UI and so there is an IAutoEParamDlg that works exactly the same way as the IAuotMParamDlg.

Parameters

hwMtlEdit	The window handle of the materials editor.
imp	The interface pointer for calling methods in 3ds Max.

Returns

A pointer to the created instance of a class derived from ParamDlg.

Implemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

SvTraverseAnimGraph()

CoreExport SvGraphNodeReference SvTraverseAnimGraph ( IGraphObjectManager *  gom, Animatable *  owner, int  id, DWORD  flags  )

virtual

Remarks

This method is available in release 3.0 and later only.

This method traverses the graph of objects in the 3ds Max scene, adding desired objects to the schematic view. Developers can specialize this behaviour by overriding this method and adding whatever objects are interesting to the schematic view. Objects are added to the schematic view by calling IGraphObjectManager::AddAnimatable(...). Reference lines are added to the schematic view by calling IGraphObjectManager::AddReference(...). Implementers of this method should call it recursively to process other objects in the scene.

See Class IGraphObjectManager.

Parameters

gom	Points to the schematic view window manager.
owner	The owning animatable.
id	This is usually the sub-anim number (but can actually be any value the developer chooses).
flags	See Flags for AddAnimatable() and SvTravereseAnimGraph().

{ return FALSE; }

SetupGfxMultiMaps()

virtual void SetupGfxMultiMaps ( TimeValue  t, Material *  mtl, MtlMakerCallback &  cb  )

inlinevirtual

Remarks

This method is called to initialize the interactive renderer Material passed with the properties of this MtlBase.

If a MtlBase (material or texmap) wants to display multiple textures in the viewports, it implements

SupportsMultiMapsInViewport() to return TRUE, and implements SetupGfxMultiMaps to store the necessary information in the Material passed in, including the TextureInfo's for each texture.

The MtlMakerCallback passed in to SetupGfxMultiMaps provides functions to help in setting up the "Material" data structure. The function NumberTexturesSupported() lets you know the capabilities of the current hardware, so you can adapt accordingly. The function GetGfxTexInfoFromTexmap fills in the fields of a TextureInfo except the texHandle and texture ops.

The implementation of SetupGfxMultiMaps must create the "texHandle" for each of the textures described in its TextureInfo array. It typically does this by calling the submap's GetVPDisplayDIB() method, and then creates the texHandle by calling the callBack function MakeHandle(bmi). To avoid doing this calculation when not necessary it is best to save the texHandles along with their validity intervals. Then when SetupGfxMultiMaps is called, if valid texHandles are already in hand they can just be used without recomputing.

Parameters

t	The time at which to evaluate the material.
mtl	Points to the interactive renderer material to update.
cb	This callback object is provided as a helper to fill in the Material properties above. See Class MtlMakerCallback.

Default Implementation:

{}

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSPluginMtl, and MSMtlXtnd.

GetInterface() [1/2]

virtual CoreExport void * GetInterface ( ULONG  id )

virtual

Remarks

This method provides a mechanism for extending the class in the future. In 3ds Max 4.0 there are new interfaces that are accessed by passing an id to this method and it will respond by returning the corresponding interface pointer.

This method has been used however for a different purpose. It currently is used to determine if an object is of a particular class. With controllers for example, there is one base class Control, however there are many super classes (CTRL_FLOAT_CLASS_ID, CTRL_SCALE_CLASS_ID, etc.). If you wanted to find out if a given Animatable was a controller you would need to compare its SuperClassID to all the known types and only if it wasn't one of the known types could you be sure it wasn't a controller. Having to do this is inconvenient for a developer.

Instead the Control class implements this method. It looks at the id, and if it matches a predefined constant I_CONTROL, it returns its this pointer. In this way, given any Animatable, it is easy to find out if it is a controller by simply asking for the control interface. There is a macro that does this:

#define GetControlInterface(anim)
((Control*)anim-\>GetInterface(I_CONTROL))

A plug-in developer may use this macro as follows:

Control *c = GetControlInterface(anim);

This will either be NULL or a pointer to a valid controller.

Note: Plug-in defined interfaces should be greater than the following value:

#define I_USERINTERFACE 0x0000ffff

If a plug-in implements this method for its own purposes, it would, in general, switch on the id and if it is not aware of the id it would call this method on the base class. Otherwise it could respond to the id as it needed. See the sample code below for the how the Control class implements this method.

Parameters

id	The id of the interface.

Default Implementation:

{ return NULL; }

Sample Code:

The following is the Control class implementation of this method. It looks at the id passed, and if it matches I_CONTROL it returns its this pointer. Otherwise it calls the base class method.

void* Control::GetInterface(ULONG id)
{
    if (id==I_CONTROL) {
        return this;
    }
    else {
        return Animatable::GetInterface(id);
    }
}

Reimplemented from Animatable.

Reimplemented in MSPluginTexmap, MSTexmapXtnd, MSTexmapXtnd, MSPluginMtl, MSMtlXtnd, and MSMtlXtnd.

GetInterface() [2/2]

virtual BaseInterface * GetInterface ( Interface_ID  id )

inlinevirtual

Remarks

Returns a pointer to the Base Interface for the interface ID passed. The default implementation of this method retrieves this information from the ClassDesc for the plug-in.

Any future object-based interfaces should be allocated unique Interface_IDs (you can use Gencid.exe for this) and made available through this call.

The default implementation of GetInterface(Interface_ID) looks up a standalone interface of the given ID on the object's ClassDesc. This gives access to standalone interfaces via any of a plug-in's objects, without having to dig around for the ClassDesc, so you should fall back to calling the default implementation if you don't recognize an ID in your implementation of GetInterface(Interface_ID).

Parameters

id	The unique ID of the interface to get. See Class Interface_ID.

Reimplemented from Animatable.

Reimplemented in IXRefMaterial, and MSMtlXtnd.

{ return ReferenceTarget::GetInterface(id); }

GetRefTarget()

virtual ReferenceTarget * GetRefTarget ( )

inlinevirtual

Remarks

{return this;}

SetProperty()

virtual CoreExport int SetProperty ( ULONG  id, void *  data  )

virtual

Remarks

This is a general method for adding properties, when defining a new Interface would be too cumbersome. This method provides another way to extend the class without actually adding any methods. Sample code that implements this method to add properties to the property list is in /MAXSDK/SAMPLES/CONTROLLERS/PATHCTRL.CPP. See below.

Parameters

id	The id for the property.
data	A pointer to the data to store.

Returns

Nonzero if the property was set; otherwise zero.

Default Implementation:

{ return 0; }

Sample Code:

This code is from /MAXSDK/SAMPLES/CONTROLLERS/path_cnstrnt.cpp. It is used to save the inverse kinematics user interface parameters of the path controller. It saves the property data on the aprops property list. See the Data Members at the beginning of Animatable for details on aprops.

int PathPosition::SetProperty(ULONG id, void *data)
   {
   if (id==PROPID_JOINTPARAMS) {    
      if (!data) {
         int index = aprops.FindProperty(id);
         if (index>=0) {
            aprops.Delete(index,1);
            }
      } else {
         JointParamsPath *jp = (JointParamsPath*)GetProperty(id);
         if (jp) {
            *jp = *((JointParamsPath*)data);
            delete (JointParamsPath*)data;
         } else {
            aprops.Append(1,(AnimProperty**)&data);
            }              
         }
      return 1;
   } else
   if (id==PROPID_INTERPUI) {    
      if (!data) {
         int index = aprops.FindProperty(id);
         if (index>=0) {
            aprops.Delete(index,1);
            }
      } else {
         InterpCtrlUI *ui = (InterpCtrlUI*)GetProperty(id);
         if (ui) {
            *ui = *((InterpCtrlUI*)data);
         } else {
            aprops.Append(1,(AnimProperty**)&data);
            }              
         }
      return 1;
   } else {
      return Animatable::SetProperty(id,data);
      }
   }

Reimplemented from Animatable.

Reimplemented in MSMtlXtnd.

GetProperty()

virtual CoreExport void * GetProperty ( ULONG  id )

virtual

Remarks

This method is used to retrieve a property specified by the id passed (as stored by SetProperty()).

Note for 3ds Max version 1.1:

Two new property IDs have been added:

PROPID_CLEARCACHES: When passed to a texture map or material, the material should dump any of its caches. For example, the bitmap texture responds to this by freeing the bitmap from memory. For sample code see /MAXSDK/SAMPLES/MATERIALS/BMTEX.CPP.

PROPID_HAS_WSM: When passed to an INode, will return TRUE if the node has World Space Modifiers applied to it or FALSE if it does not. For sample code see /MAXSDK/SAMPLES/IMPEXP/3DSEXP.CPP.

Note for 3ds Max version 1.2:

A new id has been created and assigned the constant:

#define PROPID_EVAL_STEPSIZE_BUG_FIXED 0x1000.

This only effects the evaluation of objects when rendering them using motion blur. Motion blur works by evaluating the object numerous times (at fractions of a frame apart) and combining these images by blending them together.

Originally, 3ds Max would make these evaluations in reverse order within a sub-frame – from the last one, to the second to the last one, back to the first one. There is a problem with this for certain plug-ins that need to compute their state from time 0 forward. For these objects, the backwards approach may be too computationally intensive.

Both the forward and backward approaches exist in 3ds Max and the developer may choose which method to use. 3ds Max interrogates the object to see how it should handle the evaluation process – either going backwards or forwards. It calls this method with id set to the constant PROPID_EVAL_STEPSIZE_BUG_FIXED. If a plug-in implements this method to return nonzero, it means the plug-in works correctly using forward stepping, and 3ds Max will use that approach. If a plug-in does not implement this method and handle the id of PROPID_EVAL_STEPSIZE_BUG_FIXED it will return the default value of zero. This means the older method of backwards evaluation will be used.

Therefore, a plug-in object that wants to handle motion blur using forward stepping should implement this method, and if passed an id of PROPID_EVAL_STEPSIZE_BUG_FIXED, should return nonzero.

Parameters

id	The id of the property to retrieve.

Default Implementation:

{ return NULL; }

Sample Code:

This code is from /MAXSDK/SAMPLES/CONTROLLERS/PATHCTRL.CPP. It is used to restore the inverse kinematics user interface parameters of the path controller. It retrieves the property data on the aprops property list. See the Data Members at the beginning of Animatable for details on aprops.

void* PathPosition::GetProperty(ULONG id)
   {
   if (id==PROPID_INTERPUI || id==PROPID_JOINTPARAMS) {
      int index = aprops.FindProperty(id);
      if (index>=0) {
         return aprops[index];
      } else {
         return NULL;
         }
   } else {
      return Animatable::GetProperty(id);

BaseClone()

virtual CoreExport void BaseClone ( ReferenceTarget *  from, ReferenceTarget *  to, RemapDir &  remap  )

virtual

This method copies base class data from an object to its clone.

This method is available in release 4.0 and later only. Virtual method.

Note

All plugins that implement a Clone() method have to call this BaseClone() method from that Clone() method with the old and the new object as parameters. The ordering in regards to when this method is called is unimportant, however this method must, of course, be called after the cloned object is created. This method allows base classes to copy their data into a new object created by the clone operation. As described in the Clone method, the Clone method should just create a new instance and then call the BaseClone method. The BaseClone method should then clones any references and sets any other necessary data. This allows classes that derive from this class to clone cleanly. See the Clone method documentation for a code example. All overrides of BaseClone() must call the base class implementation. The base class implementation copies the CustAttrib objects into the newly created object.

Parameters

from	- Points to the old object to clone.
to	- Points to the new object created.
remap	- This class is used for remapping references during a Clone.

Reimplemented from ReferenceTarget.

GetTransparencyHint()

virtual BOOL GetTransparencyHint ( TimeValue  t, Interval &  valid  )

inlinevirtual

Transparency hint indicates whether the material is potentially transparent for both rendering and viewport display, so that the renderers or viewport can decide whether to optimize it or not.

Parameters

t	The time to get the transparency hint at.
valid	The validity interval of the returned value.

Returns

Nonzero if this material is potentially transparent; Zero if it isn't.

Default Implementation:

{ return TRUE; }

{ return TRUE; }
