cloth simulation does not render correctly when rendering a frame sequence.
I have a simple falg attached to an object that renders correctly in a preview mp4 but does not simulate at all when i render a frame sequence. Bythe way please do fix the bug that i clone always renders at 60 fps. when rendering frames.. That one is super annoying.
Did you bake the cloth simulation (which should be run in By Frame mode)? After that the cloth behaves like a normal animation and should display correctly for image sequences.
