Whenever I make a curve in some region of my level, this distortion occurs, could anyone tell me why this occurs please?
If you mean that white ghosting that appears in the dark, that’s caused by the screen space reflections, which get updated over several frames, and can cause some issues like that on certain cases.
When screen space reflections have not yet finished calculating, you will see reflections from the Reflection probes. Have you configured those? Maybe that’s why you are seeing a default bright reflection when moving?
This distortion that you can see on the pillar when I move, is it treated with reflection capture?
I tried here using reflection capture but it didn’t work 
sorry… what curve is being distorted? I don’t seen anything on the pillar, it’s kind of blown out…
Hello Zanetti,
+1 for Screen Space Reflections. You should be able to verify this by disabling SSR. (Show → Lighting Features → Screen Space Reflections ) Once you verify that it is infact them, It looks like you may need to add a post process volume to tweak their settings.
@SIRTJames Watch the edge of the pillar. I think by ‘make a curve’ he means ‘come around a corner’
Cheers
Thanks for the answers, the problem happens around corners… another clearer example is here when I go around the corner and these sparkles happen
There are two images, the first shows the failure I’m referring to… and the second is the comparison when I’m stopped
even disabling the reflections options, this glow still happens
Oh, I see. That bright door is probably due to occlusion culling. Occlusion culling makes your scene render more efficiently by hiding not visible objects, but has a one frame delay for processing what’s visible and what not, causing that effect sometimes. Two options: disable occlusion culling (which could decrease performance), or make whatever is behind your geometry (sky or whatever) black.
oh yes, i removed the atmospherico fog and the exponential and the door stopped having that glow…
but what still hasn’t been resolved is the pillar… see how the light distorts it…
This distortion occurs whenever the flashlight is on… with it off, it doesn’t happen
this is a small example, which I took a screenshot to try to show how it happens, but this distortion is usually more aggressive
Maybe that’s the motion blur?
I tried to change the motion blur parameters on my camera, but even so the problem still occurs, when the flashlight is off the problem disappears, but when it is in use it continues 
How did you solve it? I’m encountering the same problem now!
Bit late to the party, but if anyone has this issue I think I know how to fix it. If you are talking about the little white lines which appear when you go around a corner then I fixed it by creating a post process volume, then going to the global illumination (I am assuming you are using lumen, if not then I don’t know how to fix it). Then in the lumen global illumination there is an option called screen traces, turn that off.
