Frame Debugger event information

The Event Information Panel in the Frame Debugger window displays information about the event such as geometry details and the shader used for a draw call.

Label	描述
	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.
	Color channel selector: Specifies which color channels of the render target to display.
	Levels: Controls the black and white intensity. Use this to isolate areas of the Game view based on light intensity.
	Output / Mesh Preview: Displays a preview of the selected event output as well as the mesh geometry in the event. For more information, see Preview.
	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	描述
	Preview: A preview of the mesh geometry Unity rendered during the event.
	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 window. If the geometry was procedural and there is no mesh asset associated, this is empty (Unity displays -).
	Preview mode: Specifies how the preview renders the mesh. The options are: • 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.
	Wireframe toggle: Toggles the mesh wireframe on and off. When enabled, the preview displays the mesh vertices and edges.

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
• Textures
• 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.

Share event information

To help you share information for a particular event, the Frame Debugger window can copy the information in the user interface to the clipboard. It can copy information for a single property, for all the properties in a properties section, or for an entire event. This means you don’t need to take one or multiple screenshots to share the results of a frame capture.

To copy a single property and its values to the clipboard, right-click the property and select Copy Property.

To copy all the properties and their values from a properties section, right-click the properties section header and select Copy All <property type> Properties.

To copy all the information from the rendering event, right-click the event header and select Copy Event Info.
