The rotation of a particle can be set here to change according to its speed in distance units per second.
Property: | Function: |
---|---|
Angular Velocity | Rotation velocity in degrees per second. |
Speed Range | The low and high ends of the speed range to which the size curve is mapped (speeds outside the range will map to the end points of the curve). |
This property can be used when the particles represent solid objects moving over the ground such as rocks from a landslide. The rotation of the particles can be set in proportion to the speed so that they roll over the surface convincingly.
