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"

Light and light highlight/spec going through walls.

I have stationary lights Room A.... and Room B should not be able to see light from them at all.. But they do miraculously.. no idea how to stop it.. both lighting and spec highlight are seen... nothing visibile in the reflection capture or reflection view mode. Light has shadows set to be on and stationary. alt text

why would i need that? I have 2 different wall meshes both facing opposite directions to block out all light. Its not like im relying on backfaces to cast shadows... full front faces are supposedly blocking the light. Yet not.

What is your lightmap resolution? Check out the density. If it's to low res, then the light can bleed out. http://puu.sh/t3WM4/4b06115139.jpg

its dence enough with 256 resolution currently on the lightmap for ceiling... and 64 on the one little modular peice. Light shines on both of those. As for the other side... its overly dence and needs to be lowered at like 512 per 2 meters wall lol.
