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"

New async texture streaming

The new async texture streaming that gets the perfect mip level for each texture in a scene is just what we need.

Looking at the code, it seems it takes into account the UV density (texel size) and the distance from the view point.as new heuristics in the deciding what to stream in. Would this be correct?

Secondly, the angle the texture is being viewed at is not being taken into account? (textures viewed edge on would have a higher texel density and so use a higher numbered mip). Was this viewed as too computationally intensive, not worth doing, to be left as a future improvement, already being worked on, was investigated and found to be worthless, some combination, or something else?

Cheers John
