Circular Motion Path for object animation

PostThu Nov 11, 2021 12:04 am

Is there any simpler method to create circular motion path for an object animation other that trying to manually draw circle with pologyn node? Elipse node does not have option "Right-click here for shape animation" in the inspector tab.

When you animate a centre control, you can create a circular path with the viewer context menu, Polyline -> Create -> Ellipse...

Alternatively, you can drag the crosshair off-centre, then in the Modifiers tab, animate the Path's Z Rotation control to get circular motion.

Thanks Daniel! The method with just dragging crosshair off-centre and animating Z Rotation in the transform node is the quick and works perfectly.

With Polygon node and context's menu Polyline -> Create -> Ellipse I am able to create perfect circle but when I use it for animation I am getting some weird results. Once I apply the circular path to the objects it is changing the angle. Even at the initial step I am not sure why in the created circle the centre point (by which I can move created polyline) is not actually in the centre. I'm making something wrong but not figured out yet what :)

Disregard my previous comment with weird results Polyline -> Create -> Ellipse. I've re tested from scratch and it works fine for animation. If I start context menu from the centre point it will also be the centre point of created circle. If I start from other place in the viewer it won't.
