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: > [@UE5 Sky Volumetric Lighting Ghosting, Any Solution?](https://forums.unrealengine.com/t/ue5-sky-volumetric-lighting-ghosting-any-solution/1283444/2): > > 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… Final result video test: Solved! --- _[View the full topic](https://forums.unrealengine.com/t/ghosting-artifacts-when-rendering-metahuman-character-motion-movie-render-queue/2675733)._
