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"

custom node: return SceneTextureLookup(uv,14,false) not working

Hello there, in Post Process material the hlsl code in a custom-node ("return SceneTextureLookup(uv,14,false);" always says [SM5] /Engine/Generated/Material.ush(1410,8-46): error X3004: undeclared identifier 'SceneTextureLookup'. In Window -> HLSL Code there is a correct function defined: float4 (float2 UV, int SceneTextureIndex, bool bFiltered) {...}

Other functions work too... So either i miss something really badly or there is something wrong with this shader function. I experienced this problem in 4.21 and 4.19.2

Maybe someone can help me with it.

regards Daniel

Gotta use scene texture material expression in your graph before the custom node.
