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"

How do I make a Spotlight display the reflecting light on an actor?

Basically my issue is when I place my Spotlight in the game it displays as the 1st screenshot, but when I do Build Lighting the reflection disappears (2nd screenshot)... Is this intended?

How would I make the Built version of the Spotlight appear as the 1st screenshot?

Hey, I don't use baked lighting so I'm not sure, but check if the doors have proper lightmap UVs. You can auto generate them: https://docs.unrealengine.com/en-us/Editor/Content/Types/StaticMeshes/LightmapUnwrapping/AutoGeneratedLightmaps

You can also try setting your spot light to Stationary before building the light.

... Finally, you can just set the spotlight to Movable, then it should always work.

I tried making spotlight Moveable and it works perfectly. Never thought that would be the solution since the light itself stays stationary regardless of what happens in-game.

Thank you again.

Good to hear that - yes, it should be fine, it will probably introduce small performance cost since it's fully dynamic now, but probably won't be something noticeable unless you have dozens of overlapping lights like that. If you want fully baked lighting (or cached, stationary) then checking the lightmaps is also worth trying. BTW. I've converted the comment into answer, so if it helped, I'd be grateful if you can accept it.
