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"

Hello, WixZ,

On the Translucency tab of your material, there is a "Lighting Mode" selector. Set it to "Surface TranslucencyVolume" and you will see the Metallic, Specular and Roughness pins enabled.

Please note that specularity on a translucent material has a lot of limitations and will probably behave different to what you expect, certainly different than what you see on an opaque material. Doing a realistic glass shader, for example, is not as straightforward as it sounds.

All the best.
