Reply To: How to Warp a Procedural Texture?

It’s an easy Unwrap, because the seat is just a modified cube:

The Creased Edges and one ‘vertical’ one (doesn’t matter which) should be Marked as Seams (CTRL+E). Then Unwrap and Straighten out the side UV’s.

I’d recommend the Fundamentals of Texturing, to get up to speed with UV’s.

There’s two of them, both are good; the CORE one is a bit shorter and uses Blender 4.2.

It’ll probably be easiest to then make two separate Materials for the sides and top/bottom, because a mask would be quite challenging to make in a case like this.
