public ParticleSystemScalingMode scalingMode ;


Control how the Particle System applies its Transform component to the particles it emits.

Hierarchy: Scale according to its Transform and all its parents. Local: Scale using only its own Transform, ignoring all parents. Shape: Only apply scale to the source positions of the particles, but not their size. The source positions are defined by the Shape module.
