I’ve been searching for a solution to this and haven’t yet found anything that solves it.

I’ve come to understand that the issue is related to anti aliasing and blur, and I have experimented with different settings to try and fix it but the problem only changes slightly.

Test 01:

_Using my standard rendering settings_

- 2560x1440

- .exr Sequence [16-bit]

- Deferred Rendering

- Anti-aliasing: Spatial Sample 1 | Temporal Sample 15 | Override AA | Method None

Test 02:

_Changed to Spatial AA with 64 Samples_

It kinda took out the ghosting but added some weird light artifacts

- 2560x1440

- .exr Sequence [16-bit]

- Deferred Rendering

- Anti-aliasing: Spatial Sample 64 | Temporal Sample 1 | Override AA | Method None

I’m using Ultra Dynamic Sky and haven’t messed with any parameters related to light.

I’ll run more tests and will update here if I find a fix.

Hopefully this can be fixed soon.

Thank you all!

Disabled Volumetric Fog in UltraDynamicSky and the problem went away… Now I have to figure out how to keep Volumetric Fog and eliminate only the ghosting issue

Using the command `r.VolumetricFog.HistoryWeight 0` in the Console Variables when rendering solved the issue – almost – completely. The remaining ghosting is practically imperceptible now.

This solution was based on a solution given by @Arkiras in the following forum post:

> Volumetric fog has a heavy temporal filter in order to make the quality/performance acceptable for realtime. You can adjust the temporal weight using the cvar: r.VolumetricFog.HistoryWeight It defaults to 0.9, lowering it should make the fog more responsive to lighting, but it will be less stable (more noise/flickering). A better solution most of the time is to just try to achieve your scattering effect some other way (most games just use camera facing billboards), there’s a good chance it wil…

Solved!
