Please don't mark this question as a duplicate, because solutions for other questions with the same error, doesn't work for me.
So I have a character model, created via ManuelBasioniLab, and I want to make an armature with automatic weights for it, so I created few bones to test that it will be working, and it doesn't work because of error.
I tried to:
- Delete half of the mesh and using mirror modifier
- Use Remove Doubles (on the first try deleted about 130 vertices)
- Use subsurf modifier
- Use decimate modifier
Nothing seems to be working, the error is still showing.
