You guys know that a GP40-2 and a GP38-2 are really similar, and I uploaded BN 2290s source files a few years ago, right? Just merge the two hierarchies (since OR has no problem with high triangle counts) and build whatever you want. That's why I put it out there in the first place. I consider it public domain, there's probably a way to get it into TSM if that's the way you roll. Decompile the model and modify it to your heart's content, if I ever decided to do a payware GP40-2 for OR, I'd start from scratch anyway.
