But, that would likely be fixed if we had more bones in the head for the tracking to use. Right now, we are limiting tracking to use a single bone in the head.

This may lead to other inaccuracies during the export/import process. But when I've created custom models and used them, like a basic sphere with 5 bones, I've found the tracking works perfectly. So I'm going to assume this is an issue wit
