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"

Translucent material render problem

For some reason, I have to use translucent material instead of opaque. And I got the render problem. If I use translucent material, the render older is weird. There are gif files below can help to understand the problem.

Its a limitation of translucency and differed rendering. Not much you can do about it.

Is that a bug?

no, its a limitation.

Try faking its transparency with just an opaque material and use the bumpoffset node, or subsurface scattering.

Sorry for replying late.

This is a good idea, and I tried it. It works well!
