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"

I'm writing this answer with the assumption that you have a large scene filled with many BSPs, thus causing slowdown.

BSPs are relatively inefficient and should not be used for creating detailed geometry (in my opinion) in most cases. They are often typically used for white boxing a level, or for simple wall and floor planes.

You can however convert them into static meshes, which should be done once you have finished arranging your BSPs, as you will not be able to revert them back from meshes to BSP. I found a tutorial here: https://www.youtube.com/watch?

If you don't like the idea of doing this, then I suggest that you either look into using 3D modeling software for your geometry (Blender is free) or I do have an alternative, if somewhat more complicated/advanced idea, which is to use level streaming to separate the BSPs into separate levels, which can be loaded and unloaded as your needs require.
