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"

Missing inputs in Translucent Material?

Hello, I was wondering why material inputs like roughness, metallic, and normal are greyed out when I choose a translucent material blend mode as shown in the screenshot below. From my understanding these should still be available and they are shown as available in UE4's docs in the example here: https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/MaterialProperties/BlendModes/ under the translucent section.

They become available when you select Surface TranslucencyVolume(or Surface PerPixel) Lighting Mode. They are pretty much useless without it.
