Hello there, I’m a complete beginner in unreal engine, I made this simple scene in blender and I noticed this strange problem happening when I move my camera around,
the edges of the camera view leave bright artifacts for a second or so and it slowly fades away
here is a video:
(4.5 MB)
sorry that the fps is really bad (my pc is not doing so good) but you can see the bright parts that fade away in a second or so
how can I fix this problem?
It’s auto exposure.
Usually, you can just tick a box in the project preferences to turn this off, but that’s broken in UE5 at the moment.
You can also drop a post process volume in the level and stop it happening, but that’s ALSO broken :-/
The only way I find to fix it at the moment, is to edit the PP volume on the camera you are using. And turn max and min exposure to 1. This will only work in game, or during a sequence. Not on the editor camera.
thanks for replying
I’m not quite sure if I understood correctly but I disabled auto exposure both in the PP volume and the project settings, I tried also placing a camera and disabling auto exposure there with no difference
however when I changed global illumination method from lumen to screen space the problem was fixed, is there any way I can fix this problem without having to disable lumen?
You can never ( at the moment ) get rid of the auto exposure bug from the editor camera. We just have to wait for a patch.
However, we done, apparently this is not the same problem.
This is a lumen problem. I’m not much of a Lumen hacker, you could try looking at the Lumen scene. If it doesn’t look like your actual scene, then the root of your problem can be hunted down there…
Show → Visualize → Lumen scene
Maybe also take a look at
sorry if you got notified by the last reply I posted I thought I fixed the issue by restarting the engine but I believe I was just imagining it
I just restarted the engine again the issue is there, when I view my lumen scene I can’t seem to see my level anymore and everything becomes very dark, does that mean anything?
Yes, probably something quite deep. I have no idea what I’m afraid. Try re-posting and showing the comparison of your scene and lumen scene.
