Turned out to be an issue with having the models in the directory with the new textures. I was extracting them from the .pak to view in CrazyBump. Dunno why this caused the issues, but once they were deleted the issues went away. I only noticed because I started a play through and the Infantry was doing really weird things and the death animations were messed up. I also had a poke around some old drives and managed to find the source files for the HD hud textures I was making. I’ve got the Help menu in game and it looks a lot nicer. Those hud graphics don’t upscale nice at all, you need to remake those by hand. I think there’s only one other I’ll need to make as most of the stuff included with RTX is good enough. Now, if only I could find those mud box files!
