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"

Dose material editor optimize power with intiger exponent?

Hey recently i watched this GDC talk about 0-1 space transformations https://www.youtube.com/watch?v=mr5xkf6zSzk

I started wondering if ue4 material compiler recognize that Power with static intiger exponent, for example 2, is just Base*Base? Any one knows secrets of Power node wroking ? :P Maybe this guys chack could be implemented to speed things up?

I know its very technical but I think its good to always look for ways of speeding shaders up :)

Material editor does not optimize that. Compilers, further down the pipeline, however, do.
