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"

Receive dynamic shadows on translucent material?

Is it possible to receive dynamic shadows on translucent material? I've seen this question, but it shows how to cast a shadow, not receive it. I've tried setting all lighting modes in material, but neither works.

Hey Slavq,

For a translucent object to receive shadows, there is some set up you need to follow which is highlighted in the documentation below. Shadowed direct lighting from all movable light types is injected into the translucency lighting volume. Light functions are also taken into account. Translucent materials receive diffuse GI from the Indirect Lighting Cache. Only one lighting sample is interpolated, at the center of the object's bounds. There is only one sample taken for the whole object, even if it is a large particle system. The indirect lighting interpolates over time if the bounds center changes, so it does not pop.

Lit Translucency


Let me know if you have questions or need additional assistance.
