Rendering Problems with Point Cloud

I’m rendering a point cloud in Unreal Engine 5 using Movie Render Queue, but I’m getting random frames that appear extremely low quality, with large pixelated squares instead of fine details. The issue is inconsistent—some frames render perfectly, while others look completely broken. I tried several settings in the movie render queue but nothing works. Thank you so much!


Hey @YUNG.FIL — MRQ sometimes resets the LiDAR point-cloud cvars between frames, which spawns those chunky “square” tiles.

Try this in MRQ → Console Variables

r.LidarPointBudget 8000000 ; keeps full-res tiles resident
r.LidarIncrementalBudget 0 ; stops the auto-budget throttle

Add ±32 warm-up frames so the cache is primed. These two tweaks usually wipe out the random low-detail frames.

If you still run out of VRAM locally, you can throw the shot at a bigger GPUs via HyperRender . One click from MRQ, picks an A6000/L40S, and locks the same cvars per frame—no more artefacts.

DM for a test! Hope that de-pixelates your point cloud!
