(Case 1089149) [Polybrush] Failed to paint vertex color

[optimise]

I try to paint the ground but nothing happen. What I expect is when I paint the ground it should at least change the color.

Actual result

So, probably the vert cols are being stripped on import or the shader isn’t supporting vert colours. Or maybe it’s just all Unity’s fault (blame LeonhardP)

I have a problem with Vertex Color paint on Polybrush too.
I have a material with a shader configured using Shader Graph (HD Pipe) to use Vertex Color (simple Lerp between two color in the R channel)… when i paint the same message appears and the object become all black… sometimes it works for some seconds, and then go black again.
I think Vertex Color Paint is not reliable at the moment… at least using shader graph shaders.
