I am working on my second project with Blender and I have a very weird bug.
I import Alembic files created with Quill and I time correct it with expressions to reproduce the stopmotion look (6fps or 12fps, converted to 25 fps).
It works well in the viewport and I already rendered my previous project with success in Cycles. Unfortunately, when I try to render my full scene with Eevee, my loops seems broken, and the animation becomes weirdly jerky and random.
On this short gif, you can see that the character animation is not smooth (sorry for the bad quality of the gif, it is limited by this website) :
When I try to unactiv some objects from rendering, it can randomly works again, but there isn't a specific object responsible of the bug.
It looks like that Eevee is randomly bugging with Expressions (or Alembic) when I have too many layers. I tried with differents Blender releases, it is still the same.
Is it a known problem ? Do you have suggestions to bypass this problem and finish rendering?
