hfBakeTimewarp.py v0.02 by henry foster, [email protected] (03/07/2014)

Bakes Scene Time Warp to selected objects, and optionally deletes the timewarp afterwards.

Usage:

import hfBakeTimewarp as hfBT

hfBT.bakeTimeWarp(objects=['object1','object2'],start=1,end=10,killWarp=1)

all flags are optional. defaults are to affect all selected objects, and use the existing playback options for start and end.
