UV Mapping (Unwrapping for Image Textures) I've done the UV Mapping (Unwrapping for Image Textures) tutorial and I've managed to successfully fill my cube with a layout.

However, my solid is a prism and I'm struggling to do the same with it.

What I did was to fill the dimensions in the transform menu x=1, y=2,4, z=3,51 and then do same steps, but my layout still keeps as cube.



Can someone help please?
Go to Object mode and ctrl A > Apply Scale, then unwrap again
