I am working on an academic project - we have been recording long mocap sequences using the Animazoo IGS-190 rig. Some of our file are around 20MB. When I try to import into Blender (now using 2.58, but had same problem with 2.4x etc) Blender stops responding - i can wait over 40mins with no apparent progress. Anyone else come across this? Am I doing something wrong?
