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"

High material instruction count for translucent material

Hello, I am just starting to work with UE4 and currently face the problem that a water material I am working on has a very high instruction count above 350. Translucency and the lighting mode Surface TranslucencyVolume amount to 3/4 of my instructions even when I all my normal map calculations. Is there any way to reduce the instruction count without sacrificing any features (e.g. good reflections)? The shader complexity view shows my PS in the deep reds. I wanted to use SSR too but it furthermore increased my instruction count to above 500 which is really bad. Here is a picture showing a simplified setup: alt text

Product Version: UE 4.18

This instruction count is normal for the given translucency lighting mode, and there is pretty much nothing you can do about it.
