Okay, I'm done. I even made a readme and everything.
THIS NEEDS TESTING like crazy. I haven't tested any of these in-game, so I don't know whether my changes make an improvement, no noticeable difference, or make things look worse.
This is on my to-do list to test, but it isn't very high up there at the moment. To help speed up the process, I'd be grateful if people would be willing to try any or all of these in-game and tell me what you see. Did the mesh make things look better? Worse? No difference? For interior set pieces, look all around, as usually only one or two things (out of dozens) had odd material properties. It'd be helpful to have "before" and "after" screenshots. If you're having trouble spotting a difference, let me know which mesh you are trying to test and I'll point out which area needs to be examined.
