Dr. Sassi, thank you for your guidance and your assistance with my questions. I wish you all the best.

that works, i think i had over think this, thank you!

Hi Dr Sassi,

Happy New Year, currently i have a cloner animation that start with the last cloner index , is there a way to reverse the animation to start with the first cloner index when the animation finish to create a loop. I had try to use the time field with sine shape and couldn't get it to reverse it. I have provide a file, hope it make sense. Thank you! loopanimation.c4d

Thanks for all the options! I have to save them all on my formula presets

Hi, that works, the other workaround i found is to add another formula on top to select a different id.
Appreciate the quick solution as always

Hi,

how do I select more than one id in the formula modifier? For example id=0 , how do I add another value to select another cloner, I try id=0and3. It didn't select cloner id 0 and 3. Thank you.

Hey Dr. Sassi,
I ended up setting up another simulation scene for the pyro and use the pyro as a force field object to advect the particle.
Thank you for providing me another solution and learn something new

Thank you!

Hi,
Is there a way to separate forces between pyro and particle groups?
I included a scene file, where I only want the gravity affect the pyro group and not the particle group. Thank you. pyro_particle.c4d

wow, thanks for the great explanation and video reference! this definitely is a better method than jumping between apps to modify the ramp

This is amazing, it would be great to get some technical and math background about the setup when you have some time. Thank you!
