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"

Need easy office light for the building floor


I have a large 3d building with furniture on 4 floors and don’t have the time to place lights in each room. Is there any way to easy light up my floorplan? It doesn’t matter if the shadow cast a little bit of or strange. Can one use the ceiling mesh as light? I don’t want the ceiling to glow just to cast light down.

a few options: in 4.20 they added a rectangle light, if you want to update then you could just put a big rect light on each floor.

you could make a bp that adds your lights in a grid for you. it be easy for me, maybe not for you. depends on what you know. here's a tutorial on that https://www.youtube.com/watch?v=H7Ayr9Ka1ZY

if you have a skylight there is an option call "lower hemisphere is solid color" turning that off will kinda light up the ceiling and the bottom parts of stuff.

if you add lightmass portals to the windows that help the light pass through them.
