ASE 3D model reference images

MotionCaptureROM.ase

Model is pure node animation of separate rigid meshes, no bones/mesh deformation

Note: this model has no bones/skeleton; the body is formed of separate rigid meshes for each segment (e.g. upper arm, lower arm, upper leg, lower leg are all separate meshses) and animation is entirely driven by changing node transformations over the animation timeline, rather than deforming vertices via bones and associated weights.

Artifacts

Animation has known artifacts, as stated in MotionCaptureROM.source.txt:

NOTE: The errors in the middle of the animation are caused by problems during recording,
it's not an importer issue.
