Hmm. Tried something else, i.e., a different shader. Seems my problem must be in dot(), normalize(), or cross(). One of those must not be working, because something that doesn't use them works. Also - I have Visual Studio installed, so an "updated" version of the DLL that Wings 3D needs, so.. maybe there is a compatibility issue with its GLSL implementation and the newer dll?
It is literally the only possible thing I can come up with for why it isn't working. But, the issue, based on looking at what did work, and what is in the one that didn't, has to be one of those commands.. Just wish I knew enough math to have a clue how to find which one. lol
