Im having trouble with ACT cgMuscle in Max8: moving the Proximal and Distal dummys does not interactively change the muscle on the viewports, but when I slide the time slider to a different frame (the object is not animated, Im only changing the time slider) the muscle jumps into the correct position from one end to the other, even if I return to frame 0 the slider the muscle is in correct position, until I move the dummys and then I have to repeat this proces to get the muscle into a correct position.
This problem also ocurs with the cgTubes, they do not follow their parent bones (even in the provided examples) until the viewports are forced to redraw (or the muslces re-calculated by the time shift, I dont now).
The odd thing is that the driven mesh itslef does get updated in the viewports, as I move the bones (or IK handles or whatever is driving the system), so the proces is correctly calculating the deformations, but not updating the display until I change the frame.
Do you think this could be a problem with my version of Max? Thanks very much for the help.
