Rotation Over Lifetime Module

Here, you can arrange for particles to rotate as they move.

Properties

Details

This setting is useful when particles represent small solid objects, such as pieces of debris from an explosion. Assigning random values of rotation will make the effect more realistic than having the particles remain upright as they fly. Also, the random rotations will help to break up the regularity of similarly-shaped particles (the same texture repeated many times can be very noticeable).
