I have an object with a Mirror, Subsurface, and Solidify modifier.

I gave it Collision in the Physics panel, but the particle system just goes through the object. I have not baked the particles before.

I tried adding a new object without any modifiers and the collision works. Does collision of the particle can be done in original object, or any something wrong with my scene?

I just wanna to make this:

This is what is happening Collision example

And my particle setting Particle setting

  • $\begingroup$ The collision physics should take all the modifiers before it into account.. Is it possible you could upload your .blend? $\endgroup$ – gandalf3 Oct 28 '14 at 5:13

You could add small slices to a plane as emitter vertex group.

Add a wind force field to blow the particles up

Compare the results of the Kill Particles checkbox from the settings of your collision object. When you don't kill them they will be deflected. Make sure the particles cannot escape through holes in your model.

Why not make your particles follow a path? If your car needs to actually be moving, parent the emitter and paths. I recall I did something similar before and it worked well.

  • $\begingroup$ No, my car not moving, i just want to make something like aerodynamics machine, just wondering with aerodynamic of my car modeling bad or good :D $\endgroup$ – Alfiano Fery Anggara Oct 28 '14 at 5:50
  • $\begingroup$ but thank you for the answer guys :D I visit this site everyday, and really help me be a pro :D Sorry for my bad english, im from Indonesia, nice to meet you :D $\endgroup$ – Alfiano Fery Anggara Oct 28 '14 at 5:50
  • $\begingroup$ Or for a more natural flowy effect you could use wind forces. $\endgroup$ – Scalia Oct 28 '14 at 14:54
  • $\begingroup$ I've been find the answer, because my object collision and the particle isn't in one layer $\endgroup$ – Alfiano Fery Anggara Oct 29 '14 at 11:08
  • $\begingroup$ Vince Scalia : yup, i'll try it. Thank you :D $\endgroup$ – Alfiano Fery Anggara Oct 29 '14 at 11:09
