Frame Debugger Event Information reference

The Event Information Panel in the Frame Debugger window displays information about the event such as geometry details and the shaderA program that runs on the GPU. More info
See in Glossary used for a draw call.

Label	Description
A	Render target selector: When rendering into multiple render targets (such as multiple RenderTextures or when also rendering to depth), this specifies which render target to display in the Game view. This is useful for example to view individual render targets in a G-buffer.
B	Color channel selector: Specifies which color channels of the render target to display.
C	Levels: Controls the black and white intensity. Use this to isolate areas of the Game view based on light intensity.
D	Output / MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary Preview: Displays a preview of the selected event output as well as the mesh geometry in the event. For more information, see Preview.
E	Event properties: Contains further information about the selected event. For more information, see Event properties.

Preview

The preview section consists of two tabs:

• The Output tab displays a preview of the selected event output.
• The Mesh Preview tab displays the mesh geometry Unity rendered in the event.

Label	Description
A	Preview: A preview of the mesh geometry Unity rendered during the event.
B	Mesh name: The name of the mesh asset in the preview. Click on the mesh name to take see the mesh asset in the Project windowA window that shows the contents of your Assets folder (Project tab) More info See in Glossary. If the geometry was procedural and there is no mesh asset associated, this is empty (Unity displays -).
C	Preview mode: Specifies how the preview renders the mesh. For more information, refer to Preview mode dropdown.
D	Wireframe toggle: Toggles the mesh wireframe on and off. When enabled, the preview displays the mesh vertices and edges.

Preview mode dropdown

Value	Description
Shaded	Renders the mesh using its material and a basic light.
UV Checker	Applies a checkerboard texture to the mesh to visualize how the mesh’s UV map applies textures.
UV Layout	Displays how the vertices of the mesh are organized in the unwrapped UV map. This view disables the Wireframe toggle.
Vertex Color	Visualizes any vertex colors that the vertices in this mesh have. If no vertices have a vertex color, this option is unavailable.
Normals	Visualizes the relative directions of the normals in the mesh with color.
Tangents	Visualizes the tangent data in the mesh with color.
Blendshapes	Visualizes blend shape deformations on the mesh. If the mesh has no blend shapes, this option is unavailable.

Event properties

The event properties section contains properties and values for the selected event. It has a Details fold-out section that contains information about the event itself and then a fold-out section for each type of shader property. If the fold-out section is grayed-out, it means that the shader in the event didn’t contain any properties of that type. For more information on the information that each section displays, see:

• Details
• Keywords
• TexturesAn image used when rendering a GameObject, Sprite, or UI element. Textures are often applied to the surface of a mesh to give it visual detail. More info
  See in Glossary
• Ints
• Floats
• Vectors
• Matrices
• Buffers
• Constant Buffers

Note: When using OpenGL and GLSL shaders, this panel displays all shader properties as being part of the vertex stage.

Details

The Details section displays information about the rendering event, such as the number of draw calls as well as the meshes that Unity rendered and the shader it used to render them.

Property	Description
RenderTarget	Defines the name of the render target.

Color Actions	Displays the actions Unity performs on the color target when: The GPU first loads the color target. For more information, refer to RenderBufferLoadAction. The GPU finishes rendering to the color target. For more information, refer to RenderBufferStoreAction.
Depth Actions	Displays the actions Unity performs on the depth target when: The GPU first loads the depth target. For more information, refer to RenderBufferLoadAction. The GPU finishes rendering to the depth target. For more information, refer to RenderBufferStoreAction.
Memoryless	Specifies the render textureA special type of Texture that is created and updated at runtime. To use them, first create a new Render Texture and designate one of your Cameras to render into it. Then you can use the Render Texture in a Material just like a regular Texture. More info See in Glossary memoryless mode mode. For more information, refer to memoryless.
ColorMask	Defines the color channel mask Unity uses for the render target. For more information, refer to ColorMask.

Clear Color	Specifies the color Unity uses to clear the render target during the selected event. If Unity doesn’t clear the render target, the display doesn’t show a color.
Clear Depth	Specifies the color Unity uses to clear the depth bufferA memory store that holds the z-value depth of each pixel in an image, where the z-value is the depth for each rendered pixel from the projection plane. More info See in Glossary during the selected event. If Unity doesn’t clear the depth buffer, the display doesn’t show a color.
Clear Stencil	Specifies the color Unity uses to clear the stencil bufferA memory store that holds an 8-bit per-pixel value. In Unity, you can use a stencil buffer to flag pixels, and then only render to pixels that pass the stencil operation. More info See in Glossary during the selected event. If Unity doesn’t clear the stencil buffer, the display doesn’t show a color.
Batch cause	Displays the reason why the SRP Batcher is unable to batch the selected rendering event with the previous rendering event. Relevant only if your application uses the SRP Batcher.
