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"

It would be better if you could fix your mesh... but you can try to set your MATERIAL as 2 sided, usually it helps... You can also select your mesh, go to Details, Lighting and check Use Two Sided Lighting...

I tried using Use Two Sided Lighting, but it still doesn't work. alt text alt text Does it make any difference that the light is a part of a particle? I also have some fire particles, but they don't go through the walls.alt text Thanks.

Have you checked your light's settings? Maybe it's hidden somewhere there.
