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"

Static lights disappear after baking?

Hey there!

I have problem with my lights building. I've both static and stationary lights in the scene. All the stationary lights are baking fine, but static lights do not at all like they've never exist. I've read all threads about lighting issues and their solutions on Unreal's Answers but none of them helped yet.

• My scene is originally created with 4.12.5 version (but I tried to open it on 4.14.3 and same problem happen)

• Machine: i5-2500K / GTX 970 / 32GB RAM / Windows 7 System

• All the lightmap stuff like resolutions, UV's etc are properly set.

• Tried to bake static point lights on a new blank level with some BSPs and it WORKED.

• The only warning I get after bake is: "SkySphereBlueprint Collision enabled but StaticMesh (SM_SkySphere) has no simple or complex collision."

Would be super-grateful for any suggestions, Thank you.

Product Version: UE 4.12

Do your Static Meshes have proper Lightmaps and the Resolution of them is high enough?

Yes, of course, like I wrote above, it's all set properly.

In case you guys are still having issues, try checking project settings that static lights are enabled:

project settings, allow static lighting

Next thing to check is that you aren't an idiot like me who disabled baked lighting ._.

I am having the same issue. I've found that if I change the attenuation value, then set it back to what it was, the lights pop back on.

It's super annoying to have to do this every time after you bake.

If anyone has a better method, please let me know.

edit: This is in 4.16

click on one of the lightmaps and save it, then close that window and click the scene.

hi guys!I have no idea in lighting but testing things i found some things. 1- when a material is 100% metallic, it bounces all the light, so it is dark, and that's why i thought that the lights didn't work. 2- the static lights only create the fixed final color on the static elements around it and the "residual air light" that iluminate a little the dynamic objects that came closer in real-time game. The only way I found to really illuminate powerfully a dynamic object that comes closer (like the chararcter) is turning the static lights into stationary lights (dynamic lights too but they are much more expensive)

hope it helps
