The amount the Automatic Memory Manager increases the memory allocated for Particles by. When adding a new Particle, if we discover that the Number Of Active Particles has reached the Max Number Of Particles, the Automatic Memory Manager will increase the Max Number Of Particles by the Increase Amount. For example, if the Increase Amount is set to 2.0, then the Max Number Of Particles will be doubled (200%). If it is set to 3.0 it will be tripled (300%). If it is set to 0.5, the Max Number Of Particles will be increased to 150%.
NOTE: This value is clamped to the range 1.01 - 10.0 (i.e. 101% - 1000%).
NOTE: The Automatic Memory Manager will never increase the amount of memory to be more than what is required by the Absolute Max Number Of Particles.
NOTE: Default value is 2.0.
