I got blender into a somewhat strange state after I decided to add some vertex colours to my sculpt for better visibility.
As I load the save file I cannot paint the face sets anymore, not can I paint the mask. 'Invert mask' would do nothing.
Creating a new mesh and trying to sculpt it won't work.
Effectively, I'm forced to go back to my older save, or copy everything to a new document.
I think the only things I did to get here was:
- set up the vertex paint material
- tinker with the viewport display to show vertex colours
- actually paint some over the mesh
Any advice on how can I force the document back into an usable state?
Note 1: Here's the blend file featuring the problem.
Note 2: The overlays are indeed enabled.
