[André Irniger] ” Therefore just put a Null object onto your sphere as child and put it in the middle of the sphere (and let the Tracer just trace the Null). Then you just get 1 line. Also, use a really simple form to trace, like a square (not a 24 segment circle). “

Ok, I did it! Probably there are a lot of ways to do that, but if I use the null object as you suggested, C4D doesn’t render a simple line, even with the sweep NURBS tool. So, under the sweep NURBS tool, I put a little circle.

This is the structure:
- Object1
|-- Null Object (with target: Object1; Limit: From End; Amount: 30)

- Sweep NURBS
|-- Circle (a small small circle)
|-- Tracer (with trace link: Null Object)

If, instead of the circle, I put the Null Object, nothing happens. With the little circle, everything goes fine!

Thank you all very much!

Thank you for your answers. My question is that I don’t want a clone or a trace of the object, just the path that the object did. So, if I have a sphere that moves along a spline, I would like to simply add a little trail to it.

I tried to use the Sweep NURBS and the MoGraph trace tool as you suggested, but it clones the object with an enormous load for the CPU.

The trail I had in my mind was just a line (a curve) that reminds the observer where my object was.

Sorry for my English. I hope I have explained better.

Hi,
I don’t understand… what do you mean with “comp”?

I’m trying to render the trail (or something like that), but it’s not shown in the output file (and during the rendering)… I need to make visible the last movement of the object.
