So I am trying to use mesh paint to blend two materials. however, I cannot seem to get it right.
I connected the red channel of a vertex color to the alpha of some lerps, like explained in this tutorial:
I then enter the Mesh Paint tool, and paint the mesh's red channel black (I can tell when I enter the R view mode), but I can still only see the "B" textues of the lerp.
What am I missing?
Is it possible to do it using Depth Bias instead by the way? I only want the blend to be around edges anyway. But I can't tell how to use depth bias to blend two texture samples.
