Quick answer: Unreal skeletal mesh swapping to low LOD during a cinematic close-up? LOD selection uses screen size; cinematic close-ups may exceed projection assumption - set forced LOD during cinematics.
Hero close-up: character LOD drops to LOD 3 because the screen size jumped past the bias threshold.
Force LOD during cinematic
SkelMesh->SetForcedLOD(0);Locks to highest detail. Restore after cinematic.
Or raise screen-size threshold
LOD bias settings; raise the threshold for LOD swap. Hero characters stay LOD 0 longer.
Cinematic-specific LOD distance
Custom LOD distance for cinematic cameras. Cameras tagged; LOD respects.
“LOD selection depends on camera. Cinematic cameras differ.”
If you ship cinematics, the LOD-during-cinematic policy is its own concern. Force-LOD is the cheap fix.
