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"

It should go inward if you use a negative number value instead of a positive one (for example unreal reads "10" as 10 unit UP, so if you want 10 unit DOWN instead you can multiply that by -1 and that should do the trick. As typically textures go from 0 to 1 in color value, they'll always go up unless you modify the value in some way with the power of math :P)
