I believe MR did them but they didn’t turn out as well as he’d hoped. Something about the smoke effects or something.
I think someone else did too. I believe kewlfish did Rey’s training sequence, the underground caves on Pasaana, the encounter with Kylo Ren’s TIE fighter and pointing the saber at Zorii Bliss. I believe him or someone else also did the Force bond duel as well.
