Is there a way to animate instance points on a curve in a loop in geometry nodes? I have a curve object on which I want the instanced objects to slide along, without creating a gap after them. The offset between the instanced objects should stay constant.
You can sample the curve's 0-1
Curve Parameter on its
Points domain. Then a function of it is available to a Set Position on the points the curve has been converted to.
To get the loop, the
Curve Parameter is offset, and Wrapped back to the 0-1 range. The position of that modified parameter is sampled back off the curve:
Once the points are offset down the curve, a collection of objects can be instanced on them. The offset can be exposed in the GN modifier, and keyframed.
