I was just playing with blender 2.8 particle systems and I wanted to make my particles follow a curve. I created a torus knot path using the Torus Knots+ plugin but it doesn't seems to work. I managed to get it working with more classical curves (hand drawn bezier and nurbs) but not this one.

Is there any trick I'm not aware to get it working ?


  • $\begingroup$ A torus knot is not a curve but a mesh. It won't work as a path to follow, but it could work as a collision object. Else make a bézier curve that has the shape you are after. $\endgroup$ – user1853 Mar 6 '19 at 19:52
  • $\begingroup$ Actually, there's a curve version of the torus knot plugin. Althought it also generates a surface mesh by default, you can deactivate it to only keep a poly, bezier or nurbs curve. This can be verified in edit mode. Still, the physic engine doesn't seem to recognize it as a true curve object. $\endgroup$ – ivles Mar 7 '19 at 8:23

I eventually found why it wasn't working as expected. In the object data panel, the Path animation must be ticked for the curve guide to work. It is ticked by default for Bézier curve but not for torus knots.
