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"

Is there some way to animate noise in the material, like to simulate heat growing from a hot surface?

otherwise: is there a good practice on how to produce a "heat refraction" material ?

Sure no problem. The noise node works by returning psuedo-random values based on the supplied Position input. All you need to do is take "Time" times a vector direction and add the result to your position. That is all panners do internally is add an incrementing vector.
