This test was done using the two pose walk cycle method mentioned above: A -- 30 frame walk cycle for one figure created in Posers walk designer. B--Frame 1 and frame 8 poses saved to pose dots. C--All frames deleted. D--29 frames added for total of 30. E--Previously saved frame 1 and 8 pose dots applied at frames 1 and 8, again respectively at frames 16 and 23 except mirrored. F--All finger/thumb keys deleted. G--Saved as a 30 frame animated pose. From there I closed the file, opened the file with five figures, deleted all frames, added 29 frames and applied the walk cycle from step G to each of the five figures. The entirety of this little string of tasks only takes a few minutes. This eliminated about ninety percent of the keys. (note that this leaves you with a file that is much easier to edit and fine tune than the massive jumble of keys generated by walk designer). You can go further and eliminate a lot more keys if you want, and it might make the difference because this test *almost* allowed me to do usable scrubbing. Still too slow on my system in both Poser and Carrara though. Frankly, I just use other methods to check motion as needed because I think my system just isnt stout enough to handle scrubbing in a lot of situations. I dont really think of it as a flaw in any app.
