 - **Mesh Sharing**: Particle simulation results are shared within the same group. A large number of the same effects can

 - **Position Mode**: Emission position mode.

-- **Auto Scaling**: `Transform.lossyScale` (=world scale) will be set to `(1, 1, 1)` on update. It prevents the

+- **Use Custom View:** Use this if the particles are not displayed correctly due to min/max particle size.

 - **Rendering Order**: The ParticleSystem list to be rendered. You can change the order and the materials.
