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"

1 answer: sort voted first

The answer to this is that texture samples are almost always faster than procedural generation. You're talking about looking up a value versus calculating the value first. That said, the best results will probably be a hybrid. You can use maths to calculate the large details, and textures to add small variation. You may find you get better performance by baking all the calculation to textures, though.
