I have a light inside of a wire (simple bezier curve) in Blender 2.8 and I'm wondering how I can get it to animate and move inside of the wire curve? I'd like it to follow all the curves and loops of the wire itself.

Current wire animation is just a single frame for now

I'm looking for a faster way than hand-animating it with individual keyframes.

    $\begingroup$ What have you tried so far? There are many very similar questions about objects following paths answered on Blender's StackExchange. Is there a particular challenge that you've encountered? $\endgroup$

Assuming you "wire" is an actual Bezier curve object, just animate the light along the curve with a curve constraint.

Parent the light object to curve with Path Constraint by selecting first the lamp object, then the curve and pressing Ctrl + P Set Parent to > Path Constraint.

enter image description here

Under the constraints tab click the Animate Path if necessary, and adjust the pace from the curve Object data > Path Animation > Frames

  • $\begingroup$ Is it possible to show only the animated light and not the mesh / curve where it runs along? $\endgroup$
