Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Overlapping Uv's problem

I have a real problem with the overlapping uv's problem, i have an entire mesh textured, rigged and animated that took weeks to complete without a single problem, but now some edges look bad and poorly shaded and it's because of some overlapping uv's when i used the smart UV in blender that is supposed not to overlap any UV's, the question is, am i screwed up? do i have to make the entire model's textures again? or is there a way to solve this without it?

if i recall correctly lightmaps are actually stored as a separate set of uvs. so you could in theory have one set of uvs for your textures and another for the lightmap. i believe lightmaps are stored in uv channel 1 or 2 depending on if its 0 based. what this all means is that no your not screwed you will just have to go into blender and create a second unwrapped uv.
