How to mask textures by vertex color?
I want to know if one can apply a decal texture to a vertex, just like a mesh can have vertex color on every vertex. This could be useful for simulating damage using another texture that will be visible on specific vertices, usually the contactPoints[] from the collision.
.
My approach would be to use vertex colors as a mask to determine which vertices will get the secondary texture (white color = MainTex, black color = SecTex) and then map the textures on the mesh, giving their visibility based on the color of each vertex.
.
A cool effectwould be that the textures would nicely blend due to the resulting grayscale blending of the vertex colors.
Can this work? And how can I write this kind of vertex-shader.
Any help appreciated!
