Hi, I tried everything to rig this mesh. I don’t know what happend.
I’ve been rigging for a long time but this never happend to me.
I used the mesh and rigged it like I always do with automatic weights, the mesh is symmetric, clean and I also merged by distance and deleted loose vertices. I also applied everything. I added bones and everything was fine with rigging. Then I wanted to correct one bone with the weights, and then suddently every bone didn’t worked and it always said “couldn’t find a solution for one or more bones”. I found out I can’t add any bones to the mesh, but 1 hour ago everything was fine. So, everything worked with the mesh before. Suddently I wanted to correct one bone and now everything is messed up. Why I can’t rig this mesh so suddently? Is it bc I enabled something? I don’t know. The mesh has no modifiers, nothing.
Please help, I need the mesh for a buyer who wants it quickly.

Edit: I scaled the mesh bigger and now it works again. I can’t believe this was the reason.
