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"

Light bleeding problems with desctructible meshes


Having lot's of problems with lighting as a new guy to Unreal. One of them is light bleeding. The outside is bright with a skylight and a couple of spotlights going on. How do you solve light bleeding problems in general and for destructible meshes like here?

Thank you, Domas

Hi Domas,

Destructibles and other movable meshes will not block static light during a lighting build. You can get around this by using a simple static mesh to block the light in your level when you build lighting. You can set it to be "Actor Hidden In Game" and uncheck "Visible" when you don't need it in the editor. This way when you build lighting lightmass can block the light by using that as a reference.

I hope that helps.

Thanks for the reply! But I thought that hidden in game means it's not gonna interfere with lighting.

Destructibles (being an extension of Skeletal Meshes with their own roots and bones for the chunks) do not affect how static lighting works. It is purely a dynamic object, so it can never have any influence.

If you're using a static object that is hidden in game, it will still affect static lighting because it's visible in the editor when you build lighting.
