About This File
This isn't really a tool, but it's not a mod, media, or skin either. With a lot of finagling and a nice hex editor, you can add geometry to heads for KOTOR and TSL characters. At least back in my day (my last mod was either in 2011 or 2013), this was a constant thorn in the side of models, so hopefully this tutorial is irrelevant by now. If that's the case, then I've uploaded it hear for historical significance.
Hope all is well.
