View Full Version : Setting "continuous" animation

Here's a question that I'm hoping has a simple answer...is there a way to set an animation curve to "continue forever"? I'd like to be able to (for instance) have an object rotating. I want to set one key at frame 0, at say a value of 0, and another key at frame 10, at a value of 360. I only want those two keys. Then I want to say "keep doing that forever", so that the rotation continues in an additive manner.

I've used "cycle with offset", but it asks you how many cycles you want, and then adds a bunch of keyframes, which is not what I want. In Maya this is known as Linear Post Infinity or something like that.

Thanks!

You can loop the animation. Select the track sequence in the timeline and in the AM set the Loop number. There is a little more too it than that but that is the basics for what you need.

Yeah, in Maya this thing works better. In cinema, you can loop as suggested, but it actually creates keyframes while Maya creates a infinitive non-keyframed curve

yes, rather sadly our function curves don't actually have any non destructive functions (not very function curve like then). you have two options, 1 make it into an expression instead and use xpresso governed by time (rangemapper works well for this if you don't want to get into the math of it, just plug a time nodes time/frames input into it then plug the result into whatever you want to drive), 2 use the loop with offset command :/

I make all looping animation in xpresso and it works fine for me.
Some examples of range-mapper animation can be found here (http://www.base80.com/index.php?page=xpresso1)

And I made some Rotation per minute and Beats per minutes nodes to make the setup easier RPM-BPM nodes (http://www.base80.com/index.php?page=xpresso)

Thanks guys...looks like I'm going to have to try to get my brain wrapped around xpresso a bit.
