Animation. Lock a frame

jmucchiello

I am constantly finding stuff I set in a key frame changed even when I set all keys to linear. If I accident hit UNDO, the entire animation gets borked. Is there any way to tell DAZ do not touch frame zero and the last frame NO MATTER WHAT.

I wanted to make a loop. After copying the first frame to the last frame, I started modifying the center frame. Later while working on another frame, I discover then center frame has changed. Why? Everything was set to Linear interpolation. I'd like to be able to lock frame 10. No matter what I do to the frames around it, it doesn't change unless I unlock it. Is this possible?
