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"

Object has wrapping UV's error

I get that error message when I build my scene after I made a custom mesh. I've been trying to figure out what's wrong and I can't seem to figure out how to generate UV's.

Open mesh in Mesh Editor and check next parameters:

  1. Mesh need contain UV1 for Lightmaps. If not, export to 3D programm and add secondary UV.

  2. Light Map Coordinate Index should be set to 1.

  3. If you have not change Lightmap Resolution after creation, try set a different value.
