Syntax:

simulation_substeps = <integer>

Range:

1 to 8

Default:

1

Purpose:

To control the accuracy of the particle simulation, most notably when particle collisions are being calculated. If this number is small, particles may fail to detect collisions with moving objects, or appear to bounce off objects at the wrong time. Increasing the number of substeps will produce a more accurate animation, but will also increase the amount of time needed to render each frame.

Example:

simulation_substeps = 5
