Hey, thanks again for your effort. Auto keyframing really does solve most of these problems. I’m not sure if it makes any difference, but I mainly use G9, although I don’t think that’s related. ^^
I’ve run into another issue, though it might just be user error on my side. ^^ The character is imported and rigged, everything works fine, and I pose it with the IK rig on frame 1 in the timeline. That pose is supposed to be the starting point of a loop animation. But when I copy that first keyframe and paste it to, say, frame 30 on the timeline, everything falls apart again. ^^
I also noticed something interesting: this only seems to happen when I copy the keyframe. If I duplicate it using Shift + D instead, everything works fine and doesn’t break.
I don’t have enough experience with Blender to know if that’s expected behavior, but I thought it might be helpful to mention. :)
