I'm trying to create a new kf for a model of a pump. The pump is presently animated, but it runs continuously. I'm trying to figure out how to animate it so that I can have it idle (fully stopped), start (slowly ramp up to speed), run (like it does now), and stop (slowly come to a halt, and return to an idle state) I would like the control for the pump to be right nearby, or I would just fake it by having two copies - one animated, and one not, and switch them out. If I can't pull it off, I will just move the control lever far enough away that I could realistically pull that off, but I would really like to set up the animations so that I can have it start like a real machine.
Unfortunately, I have no idea how to do it. Are there any howto's on this?
Thanks!
