You can paint on any arbitrary channel, and to use one or more channels for any arbitrary meaning for a given vertex. The reason for the negative numbering scheme for the vertex alpha and illumination channels is actually historic: It serves to preserve the meaning of existing map-channel data in older scene files before vertex alpha and illumination were added. Channel (–2): FLOAT vertex alpha (really only one value needed)Įvery geometric vertex of a mesh or poly object can be assigned up to 102 channel values (99 + 3).Channel (1): UVW standard texture mapping coordinates.Channel (2): UVW “second pass” texture mapping coordinates.The first five map channels have specific and familiar usages: The map channels are defined as triple-value channels (tuples) with a unique integer ID number ranging from –2 to 99. 3ds Max stores and manages all of these different pieces of information using the same underlying system. When using vertex paint, it is helpful to understand how 3ds Max manages vertex color, alpha, illumination, and map channels. These channels affect the transparency and shading of vertex colors, respectively.Ībout Map Channels and Vertex Color, Vertex Alpha, and Vertex Illum VertexPaint modifier also lets you paint values for the vertex alpha and illumination channels. 3ds Max shades the color, so if you have one green vertex and two white vertices for one face, for example, you'll see a gradient on that face. The Opacity button also controls the strength of the color. The more you select a face, the more it changes to the new color. The amount of color that 3ds Max applies to a vertex depends on the distance of the vertex from the position of the paint cursor on the face.

All faces sharing a vertex have the adjacent corner shaded as well. Using sub-object selection, you can also control which vertices get painted, face-by-face.
You're not restricted to only vertex-level painting. The VertexPaint modifier lets you paint vertex colors onto an object.
