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"

Ground plane causing frame rate drop

I have a flight game where the ground is actually moving rather than the aircraft, sort of a visual cheat because it's in VR and getting the player to move with a moving aircraft is problematic. So because the player position is more or less stationary, I setup the ground almost like a treadmill. Because of this fact, the ground plane cannot have baked lighting. This is causing my frame rate to suffer. It drops nearly 20-30 fps which in VR is not ideal. I also tried having an animated ground texture, but again, I can't bake that.

Any suggestions on how to work around this? Some day I may find a good tutorial on how to move with the aircraft in VR, but so far I haven't so I'm forced to use this treadmill method.
