I am having a horrible recurring problem with flipped normals in my models. Everything I try to construct seems to have them, and I can't figure out why. No matter how good they look in Truespace, by the time I have them in ModelView they're 50% transparent. Even simple cylinders develop them sometimes when I cob2pof them. Segeltouch won't open my POFs for some unknown reason, so I can't use the face-flipping tool there, does anybody have ANY idea what the )(*&$ is going on with this? Is this a common problem? Is there some technique you guys use while constructing the wireframes to avoid flipped normals?
