1) Is there a "good" or "bad" way to set up the alpha blend for vertex painting? Is it just preference based on aesthetics? 2) I'm trying to understand why this behaves the way it does: It works fine like it is, there is a 100% blend between the two diffuse textures I'm using it with. Why does it only work correctly when…
1) Not necessarily. If it works, it works. But technically, the "right" way would be the cheapest, yet most effective :) 2) Your vertex shader only works when it's connected to the Add because you're using a masking texture and you need to Multiply it to apply the Vertex Color to the white areas in the texture, then Add it…
Let me elaborate some more about my second question. That is a basic alpha blend using the red channel from my base diffuse texture. This is the same alpha blend, except instead of plugging the vertex channel back into the add node, I just used a constant 1. I'm confused as to where the vertex color node gets its…
I think I figured it out. Someone correct me if I'm wrong. Since I put in a constant one value it was taking the multiplied material and adding 1 to everything. When I clamped it down it locked it all at one. Since the I could only vertex paint between 0 and 1 I wouldn't ever be able to modify it since it was a constant.
