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"

Brightness kicks in after some time


Im having a problem in my level. Brightness in my level kicks in after I start play/preview (happens with packaged game too). As you can see in video, it kicks in after 2 mins. Same thing happens after lighting build too. I have to wait some time for editor to render it correctly. Im saying brightness because I dont know what this issue is. It might not be about brightness at all. You can skip directly to 3:00 in video.


Thank you

Product Version: UE 4.13

Hi Monster,

I noticed in the video that before the issue appeared you changed the color of the walls. You may be triggering an event that is causing the change.

It honestly looks like the textures/materials are changing on the furniture in that room rather that the brightness increasing. If it was brightness issue you would see the change occur globally on the screen, but only some assets change their color values.

If this issue always occurs after a set amount of time in your level I would check your level blueprint as well to see if you have a timed event that is changing the materials or textures in that room.

Let me know if that helps,

I dont know if its related to color changing blueprint but I realized there are several things I missed to mention.

Yes this might not be related to brightness at all. That 'kick in' at the end happens to every object in level. I should have showed other areas as well.

This issue occours after lighting build in editor too. It takes some time to kick in like this in editor after lighting build. So it shouldnt be related to any blueprint, right? I can make a video or post some pictures for it if you want.

There is only console command for fullscreen in level blueprint.

Edit: This happens even if I dont change color of the wall
