Hi everyone,
I’m encountering an issue while rendering a sequence in Unreal Engine 5. Throughout the frames, the lighting and shadows keep changing, it’s especially noticeable on the walls where it looks like a line of shadow is being dragged across the walls and flickering shadow patches on the floors.
Here’s what I’ve tried so far:
*Switched to manual exposure in (PPV).
Turned down scattering volume and enabled ray tracing in Project Settings.
- Built additional walls around the scene to avoid any light leakage.
- Rendered sequences without skylight and directional light.
- Used GPU Lightmass but the issue remains.
- Tried using Ultra Dynamic Sky, but the flickering was even worse.
Render setup:
*EXR format, anti-aliasing sample count: 64
- Game overrides: ON, 2K resolution, 30fps
Additional steps I’ve taken based on troubleshooting:
- Increased Lightmap Resolution for the meshes.
- Adjusted Ray-Traced Shadows settings, including max ray distance and samples per pixel.
- Checked my lights (both Stationary and Movable) to make sure they’re set up correctly.
- Played around with World Lightmass Settings**, including lowering the Static Lighting Level Scale to 0.1 for better shadow accuracy.
Despite these adjustments, the shadow flickering still persists. Has anyone encountered a similar issue or have suggestions for what else I can try?
Any advice would be greatly appreciated!
Thanks in advance for your help!
