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"

Why do I have light leaks?

I get sunlight leaks in seemingly random corners of rooms. Sometimes, point lights shine through walls to varying degrees. Leaks happen with dynamic and static lighting. Leaks happen with production value lighting and a lowered static lighting level. They occur with static and brush meshes. It doesn't matter if the mesh uses 2 sided lighting. I haven't tried shadow bias. That's because I can't find the setting in the documentation. I just find an example.

Typically, it occurs due to insufficient lightmap resolution, improper lightmap UV layour, or not tightly fitting meshes. This guide should be good place to start.
