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"

Since 4.14 you can use "Lighting Scenarios" to light you scene. You can also use multiple lighting scenarios (and therefore multiple backed static lights) so you can switch between day, night, evening, morning etc as much as you want. In 4.14 is a bug which messes with some lighting scenarios in a packaged version, but this one is fixed in 4.15 so I would advice you to migrate your project to the newer version.

If you don't want to use the lighting scenarios you could try to rotate or modify your directional stationary light, which would be your light source for the sunlight when you hit the trigger volume. You can either let it "jump" to a specific rotation or you can interpolate from one state to another to get a more smooth effect. But your light source has to be stationary or mobile, because this is dynamic lighting which will not work if you try to use a static light.
