I’m at the very beginning of my journey of learning about modelling/texturing/UVs, so this is probably a **really **basic question.
I’m looking over some of the free content (from the Infinity Blade Grass Lands pack) to see how people who know what they’re doing actually texture and UV their stuff. I’m looking at a staircase, and very confused by the UV layout:
Why are there UVs going off the UV map? What are these red UVs?
I’ve been following some basic ‘modelling for games’ courses etc. and thought it was pretty important to have all the UVs in 0-1 space, carefully laid out? What’s going on here? I understand that there are many UVs overlapping here because they’re pulling from the same part of a texture map containing textures for various other objects (to cut down on quantity of texture tiles), but I don’t understand these UVs going off the edge of the map.
I’m sure this is something fundamental/basic, but it’s not something I’ve seen explained anywhere.
