Particle Downsize Process
Particle Downsize process removes some part of particles according to their indices or ID.
Useful when particle number is too large to smooth displaing.
Filtering modifier makes some particles tagged as invisible. This process just remove some particles from data stored in memory for faster processing.
Downsizing Type
Select index or ID to use removing process.
Downsize number
This process removes particles and remains only particles with index (or ID) that satisfies index % n = 0.
Thus if number is set to be 5, the total number of data stored in memory would be about 1/5 of original data.
