Interface: InstanceMgr
The Instance Manager Core Interface provides access to properties and methods related to Instanced Nodes. It provides
means for collecting instances, managing material propagation to instances, making
instanced modifiers, controllers and nodes unique etc.
Properties:
InstanceMgr.autoMtlPropagation : boolean : Read|Write
When set to True , Materials assigned to an object will propagate automatically to all its instances.
Methods:
<DWORD>InstanceMgr.GetInstances <node>source <&node array>instances
instances is Out parameter
Returns the number of instances of the specified source node and the list of all instances
in the by-reference Out parameter.
FOR EXAMPLE:
|
tp = Teapot() --create a teapot
--> $Teapot:Teapot01 @ [0.000000,0.000000,0.000000]
tp1 = instance tp --instance the teapot
--> $Teapot:Teapot02 @ [0.000000,0.000000,0.000000]
tp2 = instance tp --instance it again
--> $Teapot:Teapot03 @ [0.000000,0.000000,0.000000]
tp3 = copy tp --copy the teapot
--> $Teapot:Teapot04 @ [0.000000,0.000000,0.000000]
InstanceMgr.GetInstances tp &instances -- get the instances of the original
--> 3
instances --show the returned array- all instances are there, the copy isn't
--> #($Teapot:Teapot03 @ [0.000000,0.000000,0.000000], $Teapot:Teapot02 @ [0.000000,0.000000,0.000000], $Teapot:Teapot01 @ [0.000000,0.000000,0.000000])
InstanceMgr.GetInstances tp3 &instances --get the instances of the copy
--> 1
instances -- show the returned array - the copy is the only object in it
--> #($Teapot:Teapot04 @ [0.000000,0.000000,0.000000])

<DWORD> InstanceMgr.SetMtlOnInstances <node>source <material>newMtl
Propagates the supplied new material to all instances of the specified source node.
Normally, instances can have independent materials. Using this method, all instances
can be updated to use the same material. Returns the number of instances.
FOR EXAMPLE:
|
tp = Teapot() --create a teapot
--> $Teapot:Teapot01 @ [0.000000,0.000000,0.000000]
tp.material = standard diffuse:(color 255 0 0) --assign a red material
--> Standardmaterial:Standard
tp1 = instance tp --create an instance
--> $Teapot:Teapot02 @ [0.000000,0.000000,0.000000]
tp1.pos = [100,0,0] --move the instance
--> [100,0,0]
tp1.material = standard diffuse:(color 0 255 0) --assign a green material
--> Standardmaterial:Standard
tp2 = instance tp --create another instance
--> $Teapot:Teapot03 @ [0.000000,0.000000,0.000000]
tp2.pos = [200,0,0] --move the instance
--> [200,0,0]
tp2.material = standard diffuse:(color 0 0 255) --assign a blue material
--> Standardmaterial:Standard
newMaterial = standard diffuse:(color 250 255 255) --create a white material
--> Standardmaterial:Standard
InstanceMgr.SetMtlOnInstances tp newMaterial --assign to all instances 3 --3 object affected!
|
<bool>InstanceMgr.MakeObjectsUnique <&node array>nodes <enum>multiNodeOption
nodes is In parameter
multiNodeOption enums: {#prompt | #individual | #group}
Makes the objects passed by-reference unique. Returns True on success.
FOR EXAMPLE:
|
tp = Teapot() --create a teapot
--> $Teapot:Teapot01 @ [0.000000,0.000000,0.000000]
tp1 = instance tp --instance the trapot
--> $Teapot:Teapot02 @ [0.000000,0.000000,0.000000]
tp2 = instance tp --instance it once again
--> $Teapot:Teapot03 @ [0.000000,0.000000,0.000000]
InstanceMgr.GetInstances tp &instances --get all instances
--> 3
--make the instances unique. Show a prompt to confirm the operation
InstanceMgr.MakeObjectsUnique &instances #prompt
--> true
--Check that every object is an instance of itself only.
InstanceMgr.GetInstances tp &instances
--> 1
InstanceMgr.GetInstances tp1 &instances
--> 1
InstanceMgr.GetInstances tp2 &instances
--> 1
|
<bool>CanMakeObjectsUnique <&node array>nodes
nodes is In parameter
Returns True when the specified nodes can be made unique, False otherwise.
FOR EXAMPLE:
|
tp = Teapot() --create a teapot
--> $Teapot:Teapot01 @ [0.000000,0.000000,0.000000]
tp1 = instance tp --instance the teapot
--> $Teapot:Teapot02 @ [0.000000,0.000000,0.000000]
tp2 = copy tp --copy the teapot
--> $Teapot:Teapot03 @ [0.000000,0.000000,0.000000]
--Check if the two instances can be made unique - they can
InstanceMgr.CanMakeObjectsUnique #(tp,tp1)
--> True
--Check the original and the copy - not instances, cannot be made unique
InstanceMgr.CanMakeObjectsUnique #(tp,tp2)
--> False
