Hi Robs,
2 things you could try: Sequencer captures movie without shadows
-
Disable ‘Cinematic Engine Scalability’ in render settings.
-
Disable ‘Render Unbuilt Preview Shadows in game’ in project settings. (Or maybe just try building lighting)
It also is possible to have different settings per Camera/Cinecamera.
Welcome to the forums! Let us know if any of those settings make a difference.
