Houdini: 1. Modified alembic_import_char.py to add geometry velocity motionblur functionality. On character import a timeblend and trail sop are added. The trail sop adds a v point attribute to the geometry which enables geometry motionblur per object. The object needs to be Houdini Geometry and not an alembic delayed load archive for this to work. The v attribute is read by the fur and exposed in the fur HDA.
