Controls the scale of the particles in the simulation.

PHY SET EMITTER COLLISION SCALE ID, scale#

ID

Integer
identification number of the emitter object

scale#

Float
scaling multiplier with 0.0 being at the bottom end and 1.0 at the top, as an example 0.5 will set the particles to half of their size

This command can be useful for a variety of reasons and its effect is to alter the scale of the particles in the simulation without affecting the size of the particles on screen. For example, you may want your particles to be quite large on screen and this can be achieved by altering the growth rate and maximum size. At the same time to help with collision you can scale down the particles with this command e.g. phy set emitter collision scale 1, 0.5 will have the effect of making the particles in the simulation being half the size of those displayed on screen.
