I haven't come across an issue quite like this. I spent a bunch of time googling around to see why I was having this bone weight error, and I found the following solutions, which I tried and didn't work.

  1. Making Manifold - This model is manifold and also doesn't have any intersecting faces.
  2. Correct normals - All of the normals are correct
  3. duplicate Vertices - Removed duplicate vertices
  4. Fix Scale and rotation - Done

I thought it might also be the armature, but I tried armature I've used on other models and even tried this one on other models.

No matter what I do, I just get these spikes and I can't figure out what's going on.

Thanks for your help!

  • $\begingroup$ @metaphor_set Is it blend-exchange.giantcowfilms.com ? I tried uploading with a file at 27mb and then 14mb and I just get errors. I'm obviously very new to this. $\endgroup$ – Hyper Minis Jun 15 at 0:37

I figured out the solution, but I don't quite understand the problem. I needed to decimate the character before the issue resolved itself, so I guess the issue was that I just had too many vertices.
