I've been working on retexturing Taldren's pirates and the PDN is causing me some trouble. Look at the first pic (done in the mod viewer). The model is causing the lighter triangular pathes on the rear of the saucer (Actually it's darkening the rest of the texture.) The same effect occurs on the bottom rear of the saucer as well. I've checked and it's not being caused by the lighting texture. I removed it and the problem is still there.
The second pic was done in the M1 modeling editor and you can see that the lighter triangle areas aren't there. I've also looked at it in CV and they aren't there either.
Does anyone know why it's doing this, and how to fix it?
