Frame Settings

Frame Settings are settings HDRP uses to render Cameras, real-time, baked, and custom reflections. You can set the default Frame Settings for each of these three individually from within a HDRP Asset. Open a HDRP Asset in the Inspector and navigate to the Default Frame Settings For section.

Default Frame Settings For is not just the title of the section, it also corresponds to the drop-down menu, to its right, that allows you to select which component to change the default Frame Settings for. Before you change any Frame Settings, select a component from the drop-down menu. The options are Camera, Baked or Custom Reflection, and Realtime Reflection. After you select a component, you can change the default settings HDRP uses to render a frame using that component. To make Cameras and Reflection Probes use their respective default Frame Settings, disable the Custom Frame Settings checkbox under the General settings of Cameras or under Capture Settings of Reflection Probes.

You can override the default Frame Settings on a per component basis. Enable the Custom Frame Settings checkbox to set specific Frame Settings for individual Cameras and Reflection Probes.This exposes the Frame Settings Override which gives you access to the same settings as in default Frame Settings within the HDRP Asset. Edit the settings within the Frame Settings Override to create a Frame Settings profile for an individual component.

Note that baked Reflection Probes use the Frame Settings at baking time only. After that, HDRP uses the baked texture without modifying it with updated Frame Settings.

Note: Some options are grayed-out depending on whether you have enabled/disabled them in the Render Pipeline Supported Features section of your HDRP Asset.

Frame Settings affect all Cameras and Reflection Probes. HDRP handles Reflection Probes in the same way it does Cameras, this includes Frame Settings. All Cameras and Reflection Probes either use the default Frame Settings or a Frame Settings Override to render the Scene.

Properties

Frame Settings all include the following properties:

Rendering

These settings determine the method that the Cameras and Reflection Probes using these Frame Settings use for their rendering passes. You can control properties such as the rendering method, whether or not to use MSAA, or even whether the Camera renders opaque Materials at all. Disabling these settings does not save on memory, but can improve performance.

Property Description
Lit Shader Mode Select the Shader Mode HDRP uses for the Lit Shader when the rendering component using these Frame Settings renders the Scene.
Depth Prepass Within Deferred Only available when the Lit Shader Mode is set to Deferred. If you enable Decals then HDRP forces a depth prepass and you can not disable this feature. This feature fills the depth buffer with all Meshes, without rendering any color. It is an optimization option that depends on the Unity Project you are creating, meaning that you should measure the performance before and after you enable this feature to make sure it benefits your Project.
MSAA within Forward Only available when the Lit Shader Mode is set to Forward. Enable this checkbox to enable MSAA for the rendering components using these Frame Settings.
Opaque Objects Enable this checkbox to make HDRP render Materials that have their Surface Type set to Opaque. If you disable this settings, Cameras/Reflection Probes using these Frame Settings do not render any opaque GameObjects.
Transparent Objects Enable this checkbox to make HDRP render Materials that have their Surface Type set to Transparent. If you disable this setting, Cameras/Reflection Probes using these Frame Settings do not render any transparent GameObjects.
Realtime Planar Reflection Enable this checkbox to make HDRP support real-time Planar Reflection Probe updates. HDRP updates Planar Reflection Probes every frame, because they are view dependent. Disabling this feature causes HDRP to stop updating Planar Reflection Probes every frame, but they still render in the Scene.
Transparent Prepass Enable this checkbox to make HDRP perform a Transparent Prepass. Enabling this feature causes HDRP to add polygons from transparent Materials to the depth buffer to improve sorting.
Transparent Postpass Enable this checkbox to make HDRP perform a Transparent Postpass. Enabling this feature causes HDRP to add polygons to the depth buffer that postprocessing uses.
Motion Vectors Enable this checkbox to make HDRP perform a Motion Vectors pass, allowing Cameras using these Frame Settings to use Motion Vectors. Disabling this feature means the Cameras using these Frame Settings do not calculate object motion vectors or camera motion vectors.
Object Motion Vectors Enable this checkbox to make HDRP support object motion vectors. Enabling this feature causes HDRP to calculate motion vectors for moving objects and objects with vertex animations. HDRP Cameras using these Frame Settings still calculate camera motion vectors if you disable this feature.
Decals Enable this checkbox to make HDRP process decals. Enable this on cameras that you want to render decals.
Rough Refraction Enable this checkbox to make HDRP process Rough Refraction for Cameras/Reflection Probes using these Frame Settings.
Distortion Enable this checkbox to make HDRP process Distortion. Enabling this feature causes HDRP to calculate a distortion pass. This allows Meshes with transparent Materials to distort the light that enters them.
Postprocess Enable this checkbox to make HDRP perform a Postprocessing pass. Disable this feature to remove all postprocessing effects from this Camera/Reflection Probe.
After Postprocess Enable this checkbox to make HDRP render GameObjects that use an Unlit Material and have their Render Pass set to After Postprocess. This is useful to render GameObjects that are not affected by Post-processing effects. Disable this checkbox to make HDRP not render these GameObjects at all.

Lighting

These settings control lighting features for your rendering components. Here you can enable and disable lighting features at

Property Description
Shadow Enable this checkbox to make HDRP process Shadows. This makes this Camera/Reflection Probe capture shadows.
Contact Shadows Enable this checkbox to make HDRP process Contact Shadows. Enabling this feature causes HDRP to calculate Contact Shadows for this Camera/Reflection Probe.
Shadow Masks Enable this checkbox to make HDRP support Shadow Masks.
SSR Enable this checkbox to make HDRP process Screen Space Reflections (SSR). This allows HDRP to calculate SSR for this Camera/Reflection Probe.
SSAO Enable this checkbox to make HDRP process Screen Space Ambient Occlusion (SSAO). This allows HDRP to calculate SSAO for this Camera/Reflection Probe.
Subsurface Scattering Enable this checkbox to make HDRP process subsurface scattering. Enabling this feature causes HDRP to simulate how light penetrates surfaces of translucent GameObjects, scatters inside them, and exits from different locations.
Transmission Enable this checkbox to make HDRP process the transmission effect. This allows subsurface scattering Materials to use transmission, for example, light transmits through a leaf with a subsurface scattering Material.
Atmospheric Scattering Enable this checkbox to make HDRP process atmospheric scattering. This allows your Camera/Reflection Probe to process atmospheric scattering effects such as the fog from your Scene’s Volumes.
Volumetrics Enable this checkbox to make HDRP process Volumetrics. Enabling this setting allows your rendering component to render volumetric fog and lighting.
Reprojection For Volumetrics Enable this checkbox to improve the quality of volumetrics at runtime. Enabling this feature causes HDRP to use several previous frames to calculate the volumetric effects. Using these previous frames helps to reduce noise and smooth out the effects.
Light Layers Enable this checkbox to make HDRP process Light Layers.
Exposure Control Enable this checkbox to use the exposure values you can set on relevant components in HDRP. Disable this checkbox to use a neutral value (0) instead.

Async Compute

These settings control which effects, if any, can make use execute compute Shader commands in parallel.

Property Description
Async Compute Enable this checkbox to allow HDRP to execute certain compute Shader commands in parallel.
Light List Async Enable this checkbox to allow HDRP to build the Light List asynchronously.
SSR Async Enable this checkbox to allow HDRP to calculate screen space reflection asynchronously.
SSAO Async Enable this checkbox to allow HDRP to calculate screen space ambient occlusion asynchronously.
Contact Shadows Async Enable this checkbox to allow HDRP to calculate Contact Shadows asynchronously.
Volumetrics Voxelization Async Enable this checkbox to allow HDRP to calculate volumetric voxelization asynchronously.

Light Loop

Use these settings to enable or disable settings relating to lighting in HDRP.

Note: These settings are for debugging purposes only so do not alter these values permanently.

Property Description
FPTL For Forward Opaque Enable this checkbox to make HDRP use Fine Pruned Tiled Lighting for Forward rendered opaque GameObjects.
Big Tile Prepass Enable this checkbox to make HDRP use an optimization using a prepass with bigger tiles for tile lighting computation.
Deferred Tile Enable this checkbox to make HDRP use tiles to calculate deferred lighting. Disable this checkbox to use a full-screen brute force pixel Shader instead.
Compute Light Evaluation Enable this checkbox to make HDRP compute lighting using a compute Shader and tile classification. Otherwise HDRP uses a generic pixel Shader.
Compute Light Variants Enable this checkbox to classify tiles by light type combinations. Enable Compute Light Evaluation to access this property.
Compute Material Variants Enable this checkbox to classify tiles by Material variant combinations. Enable Compute Light Evaluation to access this property.

Debugging Frame Settings

To open the Debug window, go to Window > Analysis > Render Pipeline Debug. This window allows you to debug the Frame Settings for each Camera. A list of every Camera in your Scene is on the left side of the window. Click on a Camera to select it and view its Frame Settings.

This window of the selected Camera’s Frame Settings helps you understand why a feature may not work correctly. Here, you can access all of the information that HDRP uses to render the Camera you select.

Note: The debug menu is currently only accessible for Cameras and not for Reflection Probes.

Column Description
Debug Displays modifiable Frame Setting values for the selected Camera. You can use these to temporarily alter the Camera’s Frame Settings for debugging purposes. Note that you can not enable Frame Setting features that your HDRP Asset does not support.
Sanitized Displays the Frame Setting values that the selected Camera uses after Unity checks to see if your HDRP Asset supports them.
Overridden Displays the Frame Setting values that the selected Camera overrides. If you do not check the Custom Frame Settings checkbox, or do check it and do not override any settings, this column is identical to the Default column.
Default Displays the default Frame Setting values in your current HDRP Asset.

Unity processes Sanitized, Overridden, and Default in a specific order. First it checks the Default Frame Settings, then checks the selected Camera’s Overridden Frame Settings. Finally, it checks whether the HDRP Asset supports the selected Camera’s Frame Settings and displays that result in the Sanitized column.

Interpreting the Debug Window

  • In the image above, you can see that the Light Layers checkbox is disabled at the Sanitized step. This means that, although you enabled Light Layers in the Frame Settings this Camera uses, you did not enable it in your HDRP Asset’s Render Pipeline Supported Features.
  • Also in the image above, you can also see that the Decals checkbox is disabled at the Overridden step. This means that you enabled Decals in the default Camera Frame Settings and then disabled Decals for that specific Camera’s Custom Frame Settings.
