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"

Positional Map Bake Artifacts

I was aiming to implement a triplanar decal system into character skins however since Skeletal Meshes deform I can't just use world position (as the decal would move all over the place). So I thought I'd do a positional map bake as a substitute for the World Position node however I'm seeing some pretty serious artifacts when I use it. The texture previews correctly, without any obvious visual issues, so I'm not quite sure why these artifacts are coming through when fed into the UVs of a projected decal. Anyone have any ideas on implementation/texture settings for positional bakes?
