is it the done thing to add more geo to a poly plain (example) so you can splits its uvs and overlap them for more space on uv map or is there a better way (im using a texture sheet)
not if you increase the atlas size to accommodate your textures inside. For example, if you have four objects, and each object have three 1k textures maps (Diff, Nrm, Spec) you wold end with twelve 1k textures maps. But you can use three 2k atlas texture to accommodate all your twelve 1k maps. Each object still have a 1k…
