yet another limitation.. 2004-02-26 - By Jim Rothrock
Back
I think that the problem is a result of the way mix2colors works. It looks
like you want the output of mix2colors to be (weight1 * base_color) + ((1 -
weight1) * color1). This is the operation that I would expect a color
mixing node to do, but I have not found a "mode" value that makes mix2colors
perform this operation. I just wrote my own mixColors shader and stopped
using mix2colors. If you don't want to write a shader, you can use a group
of basic scalar and basic color math shaders to perform the mixing
operation.
