This attribute represents the approximate number of polygons in the tessellated surface.
Sets how much the colliding particle’s velocity parallel to the surface decreases or increases as it bounces off the collision surface.
A value of 0 means that particles are unaffected by friction. A value of 1 makes particles reflect straight off along the normal of the surface. If Resilience is 0 while Friction is 1, the particles don’t bounce.
Only values between 0 and 1 correspond to natural friction. Values outside this range exaggerate the response.
Sets how much rebound occurs. A value of 0 makes particles collide with no bounce. A value of 1 causes particles to rebound fully. A value between 0 and -1 makes the particles pass through the surface with refraction out the back side. Values greater than 1 or less than -1 add speed to the particles.
