ParticleSystem.MainModule.scalingMode

설명

Control how the particle system's Transform Component is applied to the particle system.

Hierarchy: Scale according to its Transform and all its parents. Local: Scale using only its own Transform, ignroing 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.
