I have problem with latest version of engine 4.25, all my light start flickering like crasy.
(Latest patch 4.25.1 not help)
Video:
As a temp workaround try forcing the TemporalAA mode with high or epic quality profile for AA. This might be known bug of 4.25. Also next time you may try searching the official bug tracker and submitting a bug report if needed.
This is not works, and i check bugs report and other people issue, and not find any solution… I guess i need to make downgrade, because wait for this fix… It’s take a while. Thanks for nothing =\
Are you sure you’re definitely forcing the Temporal AA, and setting anti-alising quality to “epic” level, and not overriding those config values during runtime or with custom scalability profiles?
Also try disabling Screen-space reflections to determine if it is the issue I’m thinking about.
if this definitely doesn’t help, please fill the bug report if not sent already, be ready to make a reproducible mini bugged project for proof for the dev team, or they won’t start fixing ever.
I believe (though cannot confirm as of yet) that this is an issue with one of the several new bugs introduced in 4.25 with Auto Exposure. They drastically changed the way Eye Adaptation is calculated, but it also caused new bugs/issues.
Turn off Auto Exposure in the project settings for now until this issue is remedied, you don’t really need it for production until final launch anyways. Remember to set the Auto Exposure Bias to 0 (default is 1) as well, because there is a glitch there currently. Also, turn off eye adaptation in the editor window or else there may be a disconnect between in-game view and your editor view. Hopefully this can remedy the issue for you as it did for me, at least for now.

Only this help!
I had the same issue until I turned off auto exposure, so that’s very odd. Do remember to turn it off in both places and set exposure bias to 0 (not just in the editor window as you showed in your video, but also in project settings). But perhaps that’s linked to another issue entirely, so maybe yours is freaking out for another reason, not sure. I’ll update you if I ever can find a cause and solution.
Can you post a screenshot of your project settings with auto-exposure set to off and bias to 0? I’ll take a record of this problem along with it, thanks!
Thank for trying to help, but, doesn’t work =<div class=“lazyYT” data-youtube-id=“lmiwesAX1dE” data-width=“480” data-height=“270” data-parameters=“feature=oembed&wmode=opaque”>
I try to build engine from git, and fix that myself… This is really frustrating…
This work, but onli in editor, in game it still flickering =(
Yeah, I was right asking for disabling the screen space reflection.

Thanks a lot for sharing the solution. I can finally upgrade my project to 4.25 without the character lighting up in certain sections of the map.
Hello,
****** HERE’S FLICKERING FIX *********************
Official 4.25 and 4.26 having some glitches in calculations, namely TemporalAAHistory structure was not filled out correctly
Here’s the only solution that will surely fix for both 4.25 and 4.26 versions (building from the source and fixing engine glitch), since 4.25 will not have any more updates and 4.26 also has the same issue:
-
get Unreal 4.25 source, following link is a step by step instructions on how to get the source (no need for the building until you change buggy scripts, just when you get 4.25 source unzipped from git, run Setup.bat, after that run GenerateProjectFiles.bat ): Building Unreal Engine 4 (UE4) From Source Code / GitHub - YouTube
-
change this 2 scripts as explained in the below link, and finally, build the sourceÂ

compile your project from source (in the following link, instructions are around 8.50Â min): Building Unreal Engine 4 (UE4) From Source Code / GitHub - YouTube
Enjoy again your UE4.25/26
Cheers,
