x particles follow spline with collisions

[Brian Jones]

Not in a place to test but I would try to use xparticles dynamics and not mograph dynamics since they are separate systems, if it is all xparticles already it would be good to see the scene file

Hi Brian,
I’m using X particles, no mograph. I’ve attached a simple scene. I know within C4D’s dynamics there’s a force setting to balance the dynamics vs the mograph motion.

Here I have particles travel along a spline, and I want them to not overlap, so I added x particles PP collision. It really looks like it’s just fighting the follow spline motion. If I turn follow spline off, the collisions work correctly.

I don’t know how to correct your issue, but if you want a somewhat realistic animation of blood cells through a vein why not send the particles through a tube (sweep of ring along spline) and let them bounce off the walls?

Something like this:

I never quite get the right look that way. I’ll keep playing around, see what I can come up with.
