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"

Spot Light Incorrect Build

So I have a scene with 5 spot lights. Two are up against the feature wall in order to create a highlighted effect on the painting and door. This shows up before building. After I build, the cone of light on the wall disappears and the spot light seems to emit no light at all. Some of the other ones work but it is random. More than 2 do not overlap at a time (no X's). I know for a fact the cone shape is possible. I've attached pictures of the desired effect and the details for my light. Please help!

...an after pic would've been helpful! ;) ...you set your intensity to 4 Candelas... which is in my knowledge around 3.3 watts!!

Thanks for the reply. I increased intensity to 5000 but it had no change in effect. alt textHere is the after pic:

Do you use any IES with your lights? ...are those lights low enough: not intersecting with your light/ceiling geometry? What happens if for a test you set those spots to static?

I'm sorry, what do you mean by IES? I should mention I am moderately new to Unreal. They are low enough. I will try setting to static and let you know. Also, in a tutorial I saw on spot lights they seem to work as stationary.

No worries! https://docs.unrealengine.com/en-us/Engine/Rendering/LightingAndShadows/IESLightProfiles If it's a static scene and the light won't change (intensity, color...) then static is fine... But should work both ways! ;) If all other lights work properly (?)... maybe it's some bug? :S I would try to set them to movable if you get back the first screenshot look... or try to change units to something else (like lumens)... or delete them and place new one (copy of a working one)...

Alright, I’ll try all that tomorrow. Thanks again! Will let you know if it works. Fingers crossed it does :).

Making them static had no effect unfortunately, but thanks for the gesture.

Yes it worked! After much fiddling I got it work by copy pasting the working ones and adjusting the attenuation radius. Thanks so much!
