Is animating a headache or something? I see plenty of topics on its difficulty.
One image to render 15 - 20 min, a short animation of 6 seconds, 20 frames /sec . 120 images to render X 20 min.
à 4 seconds animation and my pc is working for more than 12 hours during the nigth (while i'm sleeping)
The day after you check it , something is wrong with i don't know the light, a hand position, whatever, you correct your timeline,
character's position etc and another 12 hours for your pc to work on it ...
