Hi,
Sorry for the ignorance but I've imported some Mocap and have done some keyframe editing.  The curve editor does not show any keyframes of curves.  I read I had to sample it which I did and the result is a straight red line in curve editor.  Any advice to get the actual curves would be appreciated.  Thank you!

I am having the same problem and am searching for solutions.  I'll let you know when i find out
