I'm working on a rendering engine but even on the first mesh is something wrong. I use assimp for mesh importing! In the Assimp Viewer it looks correct:
And in my software it looks like this:
Look at the text and you will see it is weirdly mirrored. I'm using front counter clockwise vertex winding and the texture is flipped on y coordinate - if I don't then it is completely wrong. I already tried disabling front counter clockwise winding but the texture is still inverted!
Does anybody know what else I can try?
