A vertex color map is VMap type that lets you
color the vertices (i.e., points) in your
object mesh. The color for areas in between
the vertices is averaged. (The Baker surface
shader also uses vertex color maps.) You
can see the effects of vertex color maps
in Flat shade, Smooth shade, and Texture
viewport modes. Vertex coloring is multiplied on
top of the base surface color with its texture.
This tutorial will show you how to create
a Vertex Color Map. Let's begin.

Step1: Load the source
file named "Demon_Raw" that we have
supplied or use an object of your choice.

Step 2: We need to create
a new Color Map before we can start painting.
Choose Map > Weight & Color: New
Color Map.



Step 3: Enter a name
in the input field and choose the surface that
will use this vertex color map on the apply
to surface menu.



You've just successfully created
a Color Vertex Map. Open the Advanced tab of
the Surface Editor and select the same surface
used above. You will see the map you just created
already selected on the Vertex Color Map pop-up
menu. (The Vertex Coloring is a blending
amount. You can leave it at 100%.) If in the
future you need to change the color map or remove
it from the surface, you would do it here.



Step 4: Choose Map > Weight & Color: Airbrush.
On the numeric panel, pick your map on the Weight
or Color Map pop-up menu. Choose an appropriate Radius, Strength, Color,
and Alpha.



*Note: Using your Right Mouse
button , you can change the Radius of the Airbrush
tool interactively.

Step 5: Start painting.



Note: The
density of points greatly affects how much
detail you can paint.

That about wraps up this tutorial.
Below are some examples of using Vertex Color
Maps. Happy painting!
