Just starting to get my head around animations in blender.

Rather than jumping straight into a rigged model, I smooshed together two things I had seen done in videos:

  1. Using the action editor to make an action

  2. Modifying the Bevel Factor on a bezier curve in order to grow a vine-like structure. (In my project it's a stylised trail from a spaceship.)

But, however much I change options around and use different methods of recording keyframes and swear, I can't get any keyframes recorded in the action editor, although they record fine in the dope sheet.

Is it possible to record the bevel factor as a keyframe in the action editor and I'm just doing something wrong? Or are there limits to what can be recorded in an action? How can I tell what those limits are?

it's because bevel depth is not an object property - it's curve data property. Action editor shows only one animation block (bordered with red line):

Outer animation blocks doesn't display in action editor

So what you can do - create a property in object data and make driver to manipulate bevel depth value in curve data through object data.

Howto:

  1. In object data find tab custom properties and add one:

  1. Next, open curve data side by side and press RMB on bevel depth:

Chose add driver -> single from target, and (when your cursor will be as dropper) click on value created before.

  1. So now you have value in action editor, that manipulates bevel depth:

  • $\begingroup$ Incredible. Thank you so much! I even know what to look for to know what I can add to action editor. $\endgroup$ – hainsay Jan 16 '18 at 8:18
