That won't help. Tiling a texture doesn't change the UV mapping. What is happening here is the UV dimensions are no longer consistent. The OP asks how to stop using UV altogether - tiling still uses UV.

The answer is there isn't any way to do this for clothing. For certain limited situations (a plane, a box) you can tell it to use planar mapping, but that's not good for most clothing items.

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)
