Explore the statistics and properties in the 2D Graphics module to find how much work Unity does to render 2D lights, shadows, and normal maps.
The 2D Graphics module in the Profiler window displays these statistics for the frame you select in the chart. The module is available when your project uses the Universal Render Pipeline (URP).
To open the Profiler module, follow these steps:
The chart in the 2D Graphics module displays the following categories.
| Chart | Description |
|---|---|
| Normal Textures | Displays the number of normal map textures Unity creates in the selected frame. |
| Light Textures | Displays the number of light textures Unity creates in the selected frame. |
| Shadow Textures | Displays the number of shadow textures Unity creates in the selected frame. |
| Shadow Casters Draw Calls | Displays the number of times Unity draws shadow casters in the selected frame. |
| Shadow Triangles | Displays the total number of triangles in the meshes of the shadow casters Unity draws in the selected frame. |
| Light Batches | Displays the number of 2D lights Unity draws individually in the selected frame because it can’t batch them into a single draw call. |
| Light Triangles | Displays the total number of triangles in the meshes Unity uses to render 2D lights in the selected frame. |
The details pane of the 2D Graphics module contains the 2D Graphics Statistics panel and a table of the lights and shadow casters Unity renders in the selected frame.
To make the details pane display data while Unity profiles your application, enable Live Update in the 2D Graphics Statistics panel.
The Normal Maps section contains the following property.
| Property | Description |
|---|---|
| Normal Textures | Displays the number of normal map textures Unity creates in the selected frame. Unity creates a normal map texture for each group of sorting layers that requires one. For more information, refer to Add a normal map or a mask map to a sprite in URP. |
The Lights section contains the following properties.
| Property | Description |
|---|---|
| Light Textures | Displays the number of light textures Unity creates in the selected frame. Unity creates a light texture for each blend style that a group of sorting layers uses. For more information, refer to Blend 2D lights. |
| Light Batches | Displays the number of 2D lights Unity draws individually in the selected frame because it can’t batch them into a single draw call. For more information, refer to Optimize 2D lights. |
| Light Triangles | Displays the total number of triangles in the meshes Unity uses to render 2D lights in the selected frame. Unity counts the mesh of each light once. |
The Shadows section contains the following properties.
| Property | Description |
|---|---|
| Shadow Textures | Displays the number of shadow textures Unity creates in the selected frame. |
| Shadow Casters Draw Calls | Displays the number of times Unity draws shadow casters in the selected frame. Unity draws a shadow caster once for each 2D light that lights it. For more information, refer to Shadow Caster 2D component reference for URP. |
| Shadow Triangles | Displays the total number of triangles in the meshes of the shadow casters Unity draws in the selected frame. Unity counts the mesh of each shadow caster once. |
The Timing section contains the following properties for the selected frame.
| Property | Description |
|---|---|
| Render Pass Time | Displays the time Unity spends in the main render pass of the 2D Renderer. |
| Draw Shadow Time | Displays the time Unity spends drawing shadow casters into the shadow textures. |
| Normal Pass Time | Displays the time Unity spends rendering the normal map textures. |
| Shadow Pass Time | Displays the time Unity spends rendering the shadow textures. |
The table groups the GameObjects Unity renders into a Shadow category and a Light category and contains the following columns.
| Column | Description |
|---|---|
| Name | Displays the name of the category, either Shadow or Light. Expand a category to display the GameObjects Unity renders in that category. |
| Triangles | Displays the number of triangles in the mesh of the GameObject. For a category row, displays the total for all the GameObjects in that category. |
| Vertices | Displays the number of vertices in the mesh of the GameObject. For a category row, displays the total for all the GameObjects in that category. |
| DrawCount | Displays the number of times Unity draws the light or the shadow caster in the selected frame. This column is empty for a category row. |
To select the GameObject in the Hierarchy window, select a row.
If Unity doesn’t render any 2D lights or shadow casters in the selected frame, the table displays a message that prompts you to select another frame.
