Hi, I have found other older threads about this problem but write one myself since the solutions/workarounds mentioned in the other threads don’t work for me.
So, the problem is that blender sometimes lag 1 frame when updating the armatures animation. To be more specific I have a pretty complex human’ish armature (based on the one from Rigify) and there are some bones driven by a chain of constraints that lag. I don’t know why the rest of the armature isn’t affected though.
Here is my .blend and a pic of which bones that lag:
You can see it lag if you play the animation, and the said bones immediately update if you attempt to move any of the bones.
So, any solution to this, like a script that re-update the scene each frame?
