DNeg did one sequence in the latest Matrix film. But it looked very obviously “real-time”.

But yeah otherwise I agree with your points. The person you’re replying to is vastly over estimating unreal use for final CG.

Definitely isn’t being primarily used for hero character work.

Yup. The state of the art for real-time rendering just isn't there yet for hero work. Even ILM's custom Helios renderer is only used for environments and environment-based lighting, as far as I've read. Assets, fx shots, and characters are still rendered offline.

Even with real-time rendering for environments, I'm sure there's plenty of post-processing "Nuke magic" to make it camera-ready. It's not like they're shooting UE straight to "film".

I have seen reports of Unreal Engine being used quite successfully for pre-viz, shot planning, animatics, etc., though.

I mentioned it in another comment, but Star Wars Rogue One also used it for a few shots.

Ah yeah that’s the perfect kind of show for it. It was for K3-SO for certain shots iirc.
