• Does looking at all those curves in your Blender scene induce stress and confusion? Often times importing motion capture or blocking a character animation will generate F-Curve channels that do nothing. They might just have one keyframe or maybe multiple keyframes with no change in value. You can get rid of the specific F-Curves you want with the Delete Static Channels add-on for Blender.
