Ok I’ll try to explain what happened to me, so this can be useful to somebody else.
Once again, I needed to have an object rotate for a cinematic sequence and , I may be wrong, but in my experience is not possibile to record a cinematic sequence at runtime (even if this sounds crazy, I couldn’t figure out how to do it), so I wasn’t able to use any kind of blueprint (as they only work at runtime).
Vertex animation I posted is working, but it’s like a fake rotation, so lighting is not updating as the object spins (of course I set the object and lights as movable).
So the solution for me was to animate the object via sequencer, putting keyframe on rotation.
I really hope that there are some smarter solutions to this problem, if somebody knows how to do it better, please could write it down?
Thank you
