Image texture twisted problem

If an object is turned on a diagonal in edit mode and its image texture is then twisted, is it possible to later fix this? Thanking you in advance…:o

I’m not sure I understand the problem, but yes, it is possible to fix it, just remake the UV.

What if it is not uv mapped? I’ve just put the image on as a texture mapped to the “generated” coordinates.

I presume Generated coordinates are limited, they exist for fairly simple objects. If you know you’re going to get more complex, go for UV’s.

Thanks for your time! I’ll redo it with uvs.
