I tried to bring the Carnegie Mellon mocap library into iClone but I faceplanted hard. Here is the workflow I was expecting;

1/ Import the c3d mocap data into Blender.
2/ Export as BVH data.
3/ Import to 3DX-7.
4/ (Re-target) then export as a custom iMotion.

But when I get to step 3, 3DX just freezes up. The c3d files are pretty detailed and captured @120-fps. It that just too much for iClone to handle, or is my system just too puny?

Note: I tried reducing the data in Blender using Simplify Curves. The file size for the BVH was only 6.5Mb @24-fps but 3DX still freezes on import.
