first question here and yes, I already searched and couldn't find anything for my case.
I'm trying to UV map a model I managed to get from a PS1 game as I'm doing a track conversion for rFactor 2, but the problem is that basically all the models use a perfect square projection (edge to edge on the UV) on it. My issue is that no matter what unwrap method I use (including modifying their settings), they never get unwrapped into a perfect square. If I could find a way to do that I would save a lot of manual work as like I said, all models use a square texture edge to edge.
EDIT: I found out that what I'm looking for is basically per face texture mapping but I can't find any way to do that
