I have a... weird mesh. It doesn't look that weird, but it makes the automatic unwrapping in Blender do weird things. It stretches and distorts the texture; it does all kinds of things.
This mesh, however, contains not many faces. Pretty much, each of them are rectangular, with maybe a dozen or so triangles.
The left side shows how unwrapping works now, the right side is how I'd like it to work. Forgive me the Paint picture, but I didn't deem it necessary to launch something more powerful for just a rough sketch.
Do I just manually mark every edge as a seam, or is it a hidden, existing function somewhere?
