Well, I been looking at blogs for a while now and I decided i should make one of my own. To start things off, I will post a script a made a while back that is of great use to me when animating. It's called AS_motionTrail... This script uses the standard maya motionTrail but is linked to an expression that updates what frames are shown based on your current frame.
for example: trail 3 frames before and 3 frames after;
If you are on frame 13, the motionTrail will show you frames 10, 11, 12, 13, 14, 15, and 16.
It also shows the frames and colors of the motion trail can be changed as well. when you are done, just delete the motionTrail node and all of its connections and expressions will be deleted as well. This script is very useful for timing and spacing and especially tracking arcs (a lot faster then using a whiteboard marker like how I use to).
Here's the download link:
I'd love to hear what you guys think about it. Good Animating!
