Particles and Dynamics

[selection-it]

Hello Dr. Sassy,
Please excuse my English.
I’m working with the particle system for the first time and I’ve run into a problem.
The (blue) particles should not penetrate the gray rigid spheres upon impact. They should glide along the surface of the rigid spheres and then continue flying.
Do you have a solution for this?
Thank you for your efforts.

Hi selection-it,

Here is a simple setup. Would that work for the "aerodynamic effect"?

Example:
CV4_2026_drs_25_PAad_01.c4d

Cheers

[Dr. Sassi]

P.S.: perhaps that is more along your target.

Example file
CV4_2026_drs_25_PAbp_01.c4d

The idea is simple set the velocity in a way that they "fly" along the Z axis, for example.

Cheers

Hello Dr. Sassi,

Thank you very much for your support and commitment here in the forum.
Your scene helped me a lot.

Have a nice day and a nice weekend.

[Dr. Sassi]

You're very welcome, selection-it.

Thanks for the kind feedback.

(BTW., I explored the Attract option in Flow mode, but to keep the flow along the Sphere, while keeping the following "parallel" (even with a half sphere, seems not easy, if at all.)

Enjoy your project

[Dr. Sassi]

P.S.: Here is a different idea, just with Splines

Wow, it's hard to come up with an idea like that. I'll test both versions.

Thanks for the support, it's very helpful.

Hi selection-it,

Thank you very much. Very much appreciated.

Please let me know if you need something else for this setup.

Have a great start to your week.
