After converting my project from 4.9 to 4.12, there is a material with vertex painting that I can’t get to work.
I’m receiving the following errors in the stats:
and these with the shader debugging on:
The problem seems to happen only when I connect the VertexColor node (replacing it with any scalar value doesn’t throw the error), in order to use vertex painting. This is the shader (MF_Dirt is a material function using a bool switch, a WorldAlignedTexture node, and texture samples - no more screenshots available):
If anyone can help me make heads or tails of this, it would be greatly appreciated!
