Sorry, I’m aware there are quite a few topics about weight paint not working, but I can’t figure this out.
The weight paint brush works fine on some objects, while on others it doesn’t at all:
Here’s my file:
Help once more.blend (2.8 MB)
Haven’t looked at the file, but looking at your coat, it’s in vertex mode, and no visible vertices are selected.
Still doesn’t work when I select vertices.
It worked after I applied the mirror modifier.
