Explore the properties you can use to determine the rendering order of a group of 2D GameObjects. For more information, refer to [Prevent 2D GameObjects mixing in sorting layers](/engine/6000.3/manual/unity2d/sprite/sort-sprites/use-sorting-groups.md).

| **Property**       | **Description**                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Sorting Layer**  | Sets the [sorting layer](/engine/6000.3/manual/unity-editor/editor-settings-reference/comp-manager-group/class-tag-manager.md) of the sorting group. All the child GameObjects render on this sorting layer, but keep their order. Unity renders sorting layers in the order of the list in the [Tags and layers window](/engine/6000.3/manual/unity-editor/editor-settings-reference/comp-manager-group/class-tag-manager.md).Select **Add Sorting Layer** to create a new sorting layer. |
| **Order in Layer** | Sets the sublayer of the sorting group within the **Sorting Layer**. All the child GameObjects render on this sublayer, but keep their order. Unity renders lower values before higher values.                                                                                                                                                                                                                                                                                             |
| **Sorting Type**   | Sets where Unity places the group while sorting. The options are:**Default**: Unity sorts this group with other groups at the same level in the hierarchy.**Sort at Root**: Unity sorts this group at the top level of the hierarchy, and ignores the parent sorting group.**Sort 3D as 2D**: Unity sorts this group at the top level of the hierarchy, and ignores the z value of 3D GameObjects in the group so they're sorted as 2D.                                                    |
