Particles wont stop rotating after collision

Question

I have some simple cutout particles of leaves that are set to collide only with the terrain. Once they collide I have dampen set to 1 but they continue to rotate in place on the terrain. Any idea what setting I need to change to prevent them from rotating? Here is a copy of my settings (thanks in advance!): alt text

I know this is late but you can use rotation by speed with curves because when it lays on the ground it should have speed 0

Hi mostlyhuman,

Did you find the solution to the problem you had with the rotation of the particles after collision?

I'm having the same issue here.

Hey guys, so i've nailed down how to stop rotating particles upon collision using sub Emitters, here's the settings to do so. The theory is- Fire particles which rotate with speed, when they collide with the world, they die; which in turn triggers a kill command removing the particles from the scene. when the particles die, the Sub Emitter spawns new ones which matches the rotation of the main emitter. By turning off a shape emission, they match the old translation.

hope this helps, made my brain fuzzy for a bit.
