We’ve been using a SkeletalMesh of our player for the cinamtics, switching out the ACharacter. The problem of course is that the player isn’t just one mesh… there’s the weapon, perhaps some armor and whatnot. You have to replicate all of that in the skeletal mesh you use for cinematics, so yeah it’s absolutely not convenient right now.
A bit off a tangent, but mesh emitters in particles have the same limitation and it’s just as frustrating.
