How to add a tail to my "comet"

Hi!

I have animated a sphere following a curve. Now I want the sphere to paint a line behind it. But I want the line to dissolve as time passes. Almost like it has a tail with configurable length.

Any tips on how to achieve that?
Particles?

Thanks!

If it’s on a surface you might go with Dynamic Paint.
Some good tutorials on youtube about how it works…

If it is moving in 3d space, particles with the sphere as the emitter might be the solution. Or smoke…

Thanks Motimo!

I managed to do this using dynamic paint. Exactly much what I was aiming for. :slight_smile:
