How to make the particles do not slide on the surface?

[Cheburash]

Hi!

Here is the problem:

I want to make the falling autumn leaves in Blender and put them in the video where the camera moves along the ground.

I did 3dTracking in PFTrack, and export it in Blender (Many thanks to Rigby40, the author of this tutorial:https://vimeo.com/124183959). Then I did a system of particles and the surface on which they must fall, using this lesson: https://youtu.be/vT_Tr_jzrE8.

The problem is that even at the maximum value of “Particle Friction” parameter of the surface (collision modifer), leaves (particles) continue to slide along the surface too quickly.

How to make the particles do not slide, but completely stopped? And can i do so that I can adjust the speed of sliding between a full stop and a very slow slde?

I really need some advice!
Thanks in advance!

It helps to upload your .blend? Did you also crank up the dampening?

Here’s blend file: http://www.pasteall.org/blend/35690
Here’s a video preview:

1. How can I make leaves-particles not rotate after lay on the surface?
2. How can I make particles do not pass through the surface and not “stuck” in it?
   that’s what I mean:
   
   
   
   

I really need some advice as soon as possible.
Thanks in advance!

Looks like you’re complicating things: your leaves are rigid bodies, set to collision?

I suggest you start a new scene to play with particle systems, just one emitter plane, set to emit cubes, and one floor, set to collision.
Your prototype cube is just a cube, with no physics. Play with friction and damping, and see how cubes gather on the floor. Play with rotation. Then, rebuild your scene with leaves and everything…

Very simple:
In the floor Plane physics settings check Kill particles


then in the Render tab of the particle system settings check Died.


So the particles will “die” and stay still as soon as they touch the plane, but they will be still visible.
