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"

planar reflections occlusion culling doesn't seem to be working


planar reflections occlusion culling doesn't seem to be working. they use resources when they are in the camera field of view even if they are behind other objects, not visible or if they face at the opposite direction.

is this proper and planned behavior?

i make a reflecting cube for example with planar reflections attached to each side. when the cube is not visible or since only three faces can be visible in this example, shouldn't planar reflections turn off automatically and free up system resources, exactly like they do behind the camera?

thank you.
