Particles wont stop rotating after collision

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.

I have not :/ be sure and post back if you do figure it out !

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.
