View Full Version : Characterize whithout T-stand

What is the best way to characterize a mocap file that does not include a T-pose?

If you are using the Actor, you are just going to have to eyeball placement of the Actor pieces to whatever pose you have - unless there is a point in the animation that has the character standing in a T-Pose.

The character model that receives the mocap data from the Actor can, and should, be characterized in the tradional T-Pose position, as this sets the 0 point for rotations on all the joints (this is important since any rotations).

Helpful hint: When capturing, either cinematics or in-game moves, have your actors stand in a T-Pose before and after the scene/motion. This not only allows you to create a T-Pose for the Actorization for every shot but it also allows for any movement/changes of the markers on the motion capture suit that occur while shooting.

Thanks for your reply,

I have a couple of un-characterized fbx and bhv files with different animations, walk cykles, jumping etc.
Trying to re-target those aniamtions to my skeleton results in a very strange result e.g. arms trying to follow the arms of the run for but still in t-stand.

To manually rotating all the joints back to a T-stand and then characterize works but is a lot of work.

When working with these sorts of datasets, I can tell you from painful experience, sometimes, "donkey work" is the only way to get it done.

A lot of data has to be edited, tweaked, massaged or just plain fudged to get it to work.

"donkey work" ...good expression :)

thanks for your reply!

If you have motions that have no T-Stance, simply manipulate the skeleton into a T-Stance (manually rotating the joints) and at that point, activate the characterization. You only need your skeleton in a T-Stance for the characterization step.
