Graphics Settings

Scriptable RenderLoop settings

This is an experimental setting which allows you to define a series of commands to control exactly how the Scene should be rendered (instead of using the default rendering pipeline used by Unity). For more information on this experimental feature, see the Scriptable Render Pipeline documentation on GitHub.

Camera settings

These properties control various rendering settings.

Setting:	Description:
Transparancy Sort Mode	Renderers in Unity are sorted by several criteria such as their layer number, or their distance from camera. Transparency Sort Mode adds the ability to order renderable objects by their distance along a specific axis. This is generally only useful in 2D development; for example, sorting Sprites by height or along the Y axis.
Default	Sorts objects based on the Camera mode.
Perspective	Sorts objects based on perspective view.
Orthographic	Sorts objects based on orthographic view.
Transparancy Sort Axis	Use this to set a custom Transparency Sort Mode.

Tier settings

These settings allow you to make platform-specific adjustments to rendering and shader compilation, by tweaking builtin defines. For example, you can use this to enable Cascaded Shadows on high-tier iOS devices, but to disable them on low-tier devices to improve performance. Tiers are defined by Rendering.GraphicsTier.

Property::	Function:
Standard Shader Quality	Allows you to select Standard Shader Quality.
Reflection Probes Box Projection	Allows you to specify whether Reflection Probes Box Projection should be used.
Reflection Probes Blending	Allows you to specify whether Reflection Probes Blending should be enabled.
Detail Normal Map	Allows you to specify whether Detail Normal Map should be sampled if assigned.
Enable Semitransparent Shadows	Allows you to specify whether Semitransparent Shadows should be enabled.
Cascaded Shadows	Allows you to specify whether cascaded shadow maps should be used.
Use HDR	Setting this field to true enables HDR rendering for this tier. Setting it to false disables HDR rendering for this tier. See Also: High Dynamic Range rendering
HDR Mode	The CameraHDRMode to use for this tier.
Rendering Path	The rendering path that should be used.

Built-in shader settings

Use these settings to specify which shader is used to do lighting pass calculations in each rendering path listed.

Shader:	Calculation:
Deferred	Used when using Deferred lighting, see [Camera: Rendering Path)(class-Camera)
Deferred Reflection	Used when using Deferred reflection (ie reflection probes) along deferred lighting, see [Camera: Rendering Path)(class-Camera_)
Screen Space shadows	Used when using screen space shadow.
Legacy deferred	Used when using Legacy deferred lighting, see [Camera: Rendering Path)(class-Camera).
Motion vectors	Used when using Legacy deferred lighting,. seem MeshRenderer::Motion Vectors.

Setting:	Description:
Built-in shader (Default value)	Use Unity’s built-in shaders to do the calculation.
Custom shader	Use your own compatible shader to do the calculation. This enables you to do deep customization of deferred rendering.
No Support	Disable this calculation. Use this setting if you are not using deferred shading or lighting. This will save some space in the built game data files.

Always-included Shaders

Specify a list of Shaders that will always be stored along with the project, even if nothing in your scenes actually uses them. It is important to add shaders used by streamed AssetBundles to this list to ensure they can be accessed.

Shader stripping - Lightmap modes and Fog modes

Lower your build data size and improve loading times by stripping out certain shaders involved with lighting and fog.

*Setting:*	*Description:*
Automatic (Default value)	Unity looks at your scenes and lightmapping settings to figure out which fog and lightmapping modes are not in use, and skips corresponding shader variants.
Manual	Specify which modes to use yourself. Select this if you are building asset bundles or changing fog modes from a script at runtime, to ensure that the modes you want to use are included.

Shader stripping - Instancing variants

*Setting:*	*Description:*
Strip Unused (Default value)	When a project is built, Unity only includes instancing shader variants if at least one material referencing the shader has the “Enable instancing” checkbox ticked. Unity strips any shaders that are not referenced by materials with the “Enable instancing” checkbox ticked.
Strip All	Strip all instancing shader variants, even if they are being used.
Keep All	Keep all instancing shader variants, even if they are not being used.

See GPU instancing for more information about Instancing variants.

Shader preloading

Specify a list of shader variant collection assets to preload while loading the game. Shader variants specified in this list are loaded during entire lifetime of the application. Use it for preloading very frequently used shaders. See Optimizing Shader Load Time page for details.
