Hi, I am fairly new to the concept and am having a problem with particle rotation and collisions. My scene encompases raining metal screws, which have been instanced to the particles. I have been able to create random rotation on the particles as they fall using the expression
particleShape1.rotPP2 = rand (0,360)
However, my problem is how they collide with the ground plane. I want the screws to end up flat on the floor, but at the moment some do, but others stick up in the air. I assume the answer involves some kind of expression, but am unsure how to create this.
