+| Properties | Description |
+| -- | -- |
+| Maskable | Does this graphic allow masking. |
+| Ignore Canvas Scale | Ignore the scale of the root canvas.<br>This prevents it from displaying small even in hierarchy scaling mode of `ParticleSystem`. |
+| Scale | Scale the rendering.<br>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. |
+| Shrink By Material | Shrink rendering by material.<br>Performance will be improved, but in some cases the rendering is not correct. |
+| Rendering Order | The ParticleSystems to be rendered.<br>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.
