Cycling and extrapolating function curves

One of the most common things that you need to do in animation is to…create cycles and loops.…Now we could do this by copying and pasting keyframes.…But 3ds Max provides an easier way to do this.…All I need to do is select the object and go into the Curve Editor, Graph…Editors > Track View-Curve Editor, and I'm working on rotation.…I want the logo to spin infinitely.…I'll select that curve, select all its keyframes and to get a clean loop, I'll…want to use Linear Interpolation.…

I'll click up here once again to set those tangents to Linear.…Notice, before and after the keyframed area, we're seeing a dashed line.…3ds Max calls this the Out Of Range time.…Anything before the first keyframe or after the last keyframe is known as Out Of Range.…To create a cycle, we can choose a different Out Of Range type.…We'll just go upto the Edit menu inside the Curve Editor, and go to a menu item…that says Controller.…

Controller is a program module that creates motion or animation.…Inside that Controller item, I'll choose Out Of Range Types.…
