How to make a 3d mask/Motion Path
on Mar 5, 2017 at 9:27:49 pm

I want a ball to be "orbiting" a pillar in 3 dimensions. I can do it manually be keyframing the 3d postions and looping those keyframes, but it is very hard to get it to be a perfect circle.

Making and object circle in 2d is simple enough, just make a circle shape and copy the mask path onto the position of the layer I want to move. I tried to do this in 3d, but no matter how I rotate the layer the mask is on (to be a perfect circle surrounding the central object) when i copy the mask path and paste it it still applies it as a 2 dimensional layer.

How can I get the mask (or any other "path") to occupy the z dimension so that when I paste it on the postion layer of another 3d object it will apply that position to the z depth?

If you really just want the object to move in a circle, and unless I'm misunderstanding, a simpler way would be to just move the anchor point of the orbiting object and then keyframe the rotation. You don't need a motion path.

Or make a null object, make it 3d, scoot your main object to the side a little bit, parent it to the null object, and then rotate the null object on the y axis.
