I'm very new to Cinema 4D and I have some problems with UV mapping. I'm trying to UV unwrap a sort of tube to add a texture without stretching it. I can't seem to get it to work though. I'm trying to split it along the middle line at the bottom, because this part will be covered by some stairs and a floor. I have tried relax UV etc., but it always gives me a weird result. I feel like it shouldn't be that hard because the object is fairly simple, but I feel like I've tried everything I know so far... Do you guys have any idea how to go about that? I have attached the file so that you get a better idea of what I'm talking about.
