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"

New Lighting Levels won't handle multiple skylights

I'm not sure if this a bug or work as intended but since I did not see any remark in the release note that this should not work, I assume it is a bug.

I have a project with several regular levels and two light levels. The lightlevels contain a directional light and a skysphere each for day and night sets. I add a skylight to each light level.

When only one lightlevel is visible, mapcheck reports "Multiple skylights are active, only one can be active per world"

Since the other skylight and it's level isn't loaded, it should not be active and I should be able to have one skylight per light level to provide different diffuse illumination

Product Version: UE 4.14

Hi Wallenstein,

I've submitted a ticket for this, you can track it's status here: https://issues.unrealengine.com/issue/UE-39327

From what I see when testing this the lighting will still build for the static/stationary skylight and no affect the rest of the lighting build other than having this warning. For the time being until this is fixed, you can just ignore the error.

OK, thanks, i wasn't sure if the light would build correctly. I have a day and night scenario which need different skylights plus dungeons with no skylight.

Thanks by the way for this new feature. I was beating the engine up until 4.13 to reach a similar effect but it never worked very well and didn't look good. This was a much needed feature!

I can confirm, this is still true for 4.20.1!
