Bone Heat Weighting Error - Spikes 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.


Making Manifold - This model is manifold and also doesn't have any intersecting faces.
Correct normals - All of the normals are correct
duplicate Vertices - Removed duplicate vertices
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!

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.
