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"

In the first two screenshots, you need the wall to go slightly past the floor level. The lower the better. If it's intersecting perfectly with the floor, it's not good. It needs to go lower than it.

In the second set of screenshots, I think you need to also extend the wall that's perpendicular to wall that's displaying the light bleed (looking at the last screenshot). It needs to push into the other wall quite a bit, or you could just break the wall that's displaying the bleed into two sections instead of one, to isolate them better.

I see. But if your character goes near it, it won't cast a shadow. Static lights get "baked in" into the UV Channel 2 of the wall texture whenever you build your lighting. But if you're ok with that, cool.

Have you tried turning on shadows for the light? also try splitting the surface so that it doesn't share two rooms, one wall per room.
