| Scale | Scale the rendering.
When the `3D` toggle is enabled, 3D scale (x,y,z) is supported. |
| Animatable Properties | If you want update material properties (e.g. `_MainTex_ST`, `_Color`) in AnimationClip, use this to mark the changes. |
| Mesh Sharing | Particle simulation results are shared within the same group.
A large number of the same effects can be displayed with a small load.
When the `Random` toggle is enabled, it will be grouped randomaly. |
+| Absolute Mode | The particles will be emitted at the ParticleSystem position.
Move the UIParticle/ParticleSystem to move the particle. |
| Rendering Order | The ParticleSystems to be rendered.
You can change the rendering order and the materials. |
NOTE: Press `Refresh` button to reconstruct rendering order based on children ParticleSystem's sorting order and z position.
