I'm having trouble figuring out how to accomplish this, so I thought I'd turn to the Creative Cow community. I have a model of a centrifuge that I need to have spin. It starts slowly and then gets faster and faster. Once it reaches top speed, I want to just have it cycle. So, frame 1 is a flat tangent and the rotation is 360 degrees over 30 frames. Then, it's a 360 degree rotation over 15 frames, etc. The problem is that whenever I select the rotation curve in the graph editor and tell it to cycle, it goes back to the first keyframe at frame 1, effectively stopping the spinning and starting all over again. Is there any way to have it cycle just the curve after a certain keyframe?
