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"

How did you setup the room? Is it a cube with it's normals reversed, like this?

Then you should try "Shadow Two Sided". You'll find it in the Details Tab under Lighting. alt text

To see the result, you need to build the lighting.

EDIT: Ignore my question, I failed to see you mentioned modular walls, still, "shadow two sided" could be what you are looking for.

I guess you're messes are thin and light is coming through them. Try to give them some thickness or make a shell outside so that it covers your structure and then put a lightmass surrounding your scene and then try. It should work

Thank you for the anwser. If i make a shell outside there are weird reflections in the room... I already have a lightmass importance volume arround it and I tried to add thickness but still the same result. My last try is to make a new wall, and add thickness at the beginning and reimport the mesh. Any other ideas?
