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"

Why does light appear on objects even though I made them unvisible?

Hey, I have a problem with light. Well, I created an actor and added an object and light to it. I want to make the light turn on at the touch of a button. However, when the light is off, there is still a glow on the subject which does not exist when I remove the light source. Light is stationary, with lightmass. Can you advise me something?

The object is located in a closed room, and the light was rebuilt every time I made the change. This problem does not appear when i use movable light, but i dont want to use it.

Stationary light bakes its lighting information when you build lights just like a static light source. when you turn it off(set intensity to 0) it will stop lighting dynamic objects but baked static lighting information will stay. If that candle is the only light source in the room and you want pitch black darkness you need to use a movable light source, or create a separate post process volume for the room and set Global Illumination Intensity to 0 when you turn off the stationary light.

I was afraid of that. Well, I'm going to have to use the movable option. Thanks for help :D

The ambient glow could come from an active Skylight actor or, if you already deleted/disabled all light sources, from outdated lightmaps. See if rebuilding lights helps.
