Question Animated Blender mesh doesn't match Unity - Might be bone weights????

I have an animated model made in blender with an armature. In Unity the model mostly matches what I see in Blender, but not exactly. A few vertexes are not where they're supposed to be. It seems like the weight painting from Blender isn't importing properly.

Could it be from quads getting turned into triangles at odd angles?

Import options for the model and animations are set to defaults in Unity.

 

Well, never mind. Turns out to be skin weights under Quality in Project settings.
