Object Channel Indices
The following are the indices that may be used for the object channels. These values are used in the methods Object::UpdateValidity(), Object::SetChannelValidity() and Object::ChannelValidity().
#define	TOPO_CHAN_NUM   0
	The topology channel number.
#define	GEOM_CHAN_NUM   1
	The geometry channel number.
#define	TEXMAP_CHAN_NUM   2
	The texture vertices and procedural mappings channels number.
#define	MTL_CHAN_NUM   3
	This is no longer used.
#define	SELECT_CHAN_NUM   4
	The sub-object selection channel number.
#define	SUBSEL_TYPE_CHAN_NUM   5
	This is the current level of selection number.
#define	DISP_ATTRIB_CHAN_NUM   6
	The display channel number.
#define	VERT_COLOR_CHAN_NUM   7
	The vertex colors number. This is also used for the second mapping channel.
#define	GFX_DATA_CHAN_NUM   8
	The stripping, edge list, etc. channel number.
#define	DISP_APPROX_CHAN_NUM   9
	The displacement approximation channel number.
#define	EXTENSION_CHAN_NUM   10
	The extension object channel number.

Variables
Channels
The pipeline is divided into the following channels:
const ChannelMask	TOPO_CHANNEL = (ChannelMask)(1<<0)
	The topology channel - the face or polygon structures.
const ChannelMask	GEOM_CHANNEL = (ChannelMask)(1<<1)
	The vertices of the object.
const ChannelMask	TEXMAP_CHANNEL = (ChannelMask)(1<<2)
	The texture vertices and procedural mappings.
const ChannelMask	MTL_CHANNEL = (ChannelMask)(1<<3)
	This is no longer used.
const ChannelMask	SELECT_CHANNEL = (ChannelMask)(1<<4)
	The sub-object selection channel.
const ChannelMask	SUBSEL_TYPE_CHANNEL = (ChannelMask)(1<<5)
	The current level of selection.
const ChannelMask	DISP_ATTRIB_CHANNEL = (ChannelMask)(1<<6)
	The miscellaneous bits controlling the item's display.
const ChannelMask	VERTCOLOR_CHANNEL = (ChannelMask)(1<<7)
	The color per vertex channel.
const ChannelMask	GFX_DATA_CHANNEL = (ChannelMask)(1<<8)
	The used internally by 3ds Max for stripping.
const ChannelMask	DISP_APPROX_CHANNEL = (ChannelMask)(1<<9)
	Displacement approximation.
const ChannelMask	EXTENSION_CHANNEL = (ChannelMask)(1<<13)
	The channel used by extension channel objects.
const ChannelMask	TM_CHANNEL = (ChannelMask)(1<<10)
	The ObjectState Transform that flows down the pipeline.
const ChannelMask	EDGEVISIBLITY_CHANNEL = (ChannelMask)(1<<11)
	For internal use.
const ChannelMask	DONT_RECREATE_TRISTRIP_CHANNEL = (ChannelMask)(1<<12)
	For internal use.
const ChannelMask	GLOBMTL_CHANNEL = (ChannelMask)(1<<31)
	This is no longer used.
const ChannelMask	OBJ_CHANNELS = (TOPO_CHANNEL|GEOM_CHANNEL|SELECT_CHANNEL|TEXMAP_CHANNEL|MTL_CHANNEL|SUBSEL_TYPE_CHANNEL|DISP_ATTRIB_CHANNEL|VERTCOLOR_CHANNEL|GFX_DATA_CHANNEL|DISP_APPROX_CHANNEL|EXTENSION_CHANNEL)
	All geometry channels.
const ChannelMask	ALL_CHANNELS = (OBJ_CHANNELS|TM_CHANNEL|GLOBMTL_CHANNEL)
	All object, transform and global material channels.
