Aaaa hah. Houston, we have a problem.

OK that is classic noobish UV mapping there. I've never seen it this bad on a hard prop. I've seen crap like that on clothing, but not simple walls. Wow.

So you can see that the U scale and V scale on various areas do not agree as to aspect ratio or overall scale. There are 4 different densities as far as I can see. (Nice AO render job there, BTW).

So we have three choices:

1. Remap all those areas

2. Abandon UV-based techniques. Using an image texture will become tricky then but it can be done. The issue here with procedural techniques is they are 3-D, but we really want a 2-D pattern here. 2-D is much easier with a proper UV map, even for procedurals such as my Loom.

3. Hide that crap and add new polygons (wall sections) that you design to do the job right.

Which way? I can't help with UV mapping - never done it except when I procedurally generate geometry using a script. (Geomatic - never released it - similar to matmatic, but it generates 3D geometry and matching UV coordinates using scripts.)

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
