Hello there!
I’m currently new to animating in Blender since I decided to switch from Moon Animator to Blender for realism (Making realistic animations). The issue is that when I am animating, the FPS is extremely slow and keep in mind that Frame Rate is 60 FPS.
This is the tutorial I used: https://www.youtube.com/watch?v=HDL__EYvP0U&t=865s (Though it is slightly different, that being the rig the tutorial used.)
