Hello all,

I’m a Masters student and I engage in an animation project which attempts to use Motion Capture for the first time as an animation tool. Unfortunately I have reached a point where I face constant issues with XSI (I know that many of you may say to use 3Ds max on this case but unfortunately I’m not as experienced on Max as in XSI) not accepting the motion capture data exported from Motion builder.

Some info about the data:
-The Motion Capture data is that of a character playing the violin using an optical capture system of 10 cameras.
-The capture is focused on pelvis, upper torso and arms/hands, so no markers on the fingers as the capture system with 10 cameras was struggling to cope and it would be a nightmare to clean later on. There were also no markers on the feet since the character is standing although some may argue that it would help on the swaying movement of the pelvis.
-The capture is not a blend of captures but a constant single epic of about 4 minutes 40 seconds in duration and 7.8MB in data size (thats in C3D format-about 3MB in BVH).
-The data have been captured and cleaned/smoothed in EvART from Motion Analysis and exported BVH format using Motionbuilder.

When I try to load a dummy MoCap data (as it is, not on a tagged rig) of a walk it works fine but when I try to load the proper violin MoCap data it comes up with an error of Model not being valid.

When I try on a tagged rig its just says that it could not load the BVH data.

In both ocasions (dummy walk data - violin data) a 3Ds Max rig was used as a template in Motion builder to get the BVH data.

Does anyone have an idea of what It could cause this? What could I have done wrong in Motionbuilder? Or is XSI compatibility being the problem?

I look forward to your replies and thank you in advance! :)
