whether the fixed function pipeline uses vertex colors for lighting
calculations is controlled by glColorMaterial and
glEnable(GL_COLOR_MATERIAL).
You can use a MaterialChunk with sfColorMaterial and sfBackColorMaterial
set to GL_NONE. That will make OpenGL use only the colors in the
material for lighting.
In case you are not using lighting (i.e. glDisable(GL_LIGHTING)) the
fixed function pipeline will use the vertex colors and I don't think we
have a way to _not_ pass vertex attributes that are attached to a
geometry to the GL - so a shader would probably your best (only?) option
in that case.
Cheers,
Carsten
