URP Package Samples

URP Package Samples is a package sample for the Universal Render Pipeline (URP). It contains example shaders, C# scripts, and other assets you can build upon, use to learn how to use a feature, or use directly in your application. For information on how to import URP Package Samples into your project, refer to Importing package samples.

Each example uses its own URP Asset so, if you want to build an example scene, add the example's URP Asset to your Graphics settings. If you don't do this, Unity might strip shaders or render passes that the example uses.

Camera Stacking

The URP Package Samples/CameraStacking folder contains examples for Camera Stacking. The following table describes each Camera Stacking example in this folder.

Example	Description
Mixed field of view	The example in CameraStacking/MixedFOV demonstrates how to use Camera Stacking in a first-person application to prevent the character's equipped items from clipping into the environment. This setup also makes it possible to have different fields of view for the environment camera and the equipped items camera.
Split screen	The example in CameraStacking/SplitScreenPPUI demonstrates how to create a split-screen camera setup where each screen has its own Camera Stack. It also demonstrates how to apply post-processing on world-space and screen-space camera UI.
3D skybox	The example in CameraStacking/3D Skybox uses Camera Stacking to transform a miniature environment into a skybox. One overlay camera renders a miniature city and another renders miniature planets. The overlay cameras render to pixels that the main camera did not draw to. With some additional scripted translation, this makes the miniature environment appear full size in the background of the main camera's view.

Decals

The URP Package Samples/Decals folder contains examples for decals. The following table describes each decal example in this folder.

Example	Description
Blob shadows	The example in Decals/BlobShadow uses the Decal Projector component to cast a shadow under a character. This method of shadow rendering is less resource-intensive than shadow maps and is suitable for use on low-end devices.
Paint splat	The example in Decals/PaintSplat uses a WorldSpaceUV Sub Graph and the Simple Noise Shader Graph node to create procedural decals. The noise in each paint splat uses the world position of the Decal Projector component.
Proxy lighting	The example in Decals/ProxyLighting builds on the Blob shadows example and uses Decal Projectors to add proxy spotlights. These decals modify the emission of surfaces inside the projector's volume. Note: To demonstrate the extent of its lighting simulation, this example disables normal real-time lighting.

Lens Flares

The URP Package Samples/LensFlares folder contains lens flare examples. The following table describes each lens flare example in this folder.

Example	Description
Sun flare	The LensFlares/SunFlare example demonstrates how to use the Lens Flare component to add a lens flare effect to the main directional light in the scene.
Lens flare showroom	The LensFlares/LensFlareShowroom example helps you to author lens flares. To use it: 1. In the Hierarchy window, select the Lens Flare GameObject. 2. In the Lens Flare component, assign a LensFlareDataSRP asset to the Lens Flare Data property. 3. Change the Lens Flare component and data properties and view the lens flare in the Game View. Note: If the text box is in the way, disable the Canvas in the scene.

Lighting

The URP Package Samples/Lighting folder contains examples for lighting. The following table describes each lighting example in this folder.

Example	Description
Reflection probes	The example in Lighting/Reflection Probes uses reflection probes to create reflection maps for a reflective sphere GameObject. This sample shows how the Probe Blending and Box Projection settings can change the reflection within a scene that uses reflection probes.

Renderer Features

The URP Package Samples/RendererFeatures folder contains examples for Renderer Features. The following table describes each Renderer Feature example in this folder.

Example	Description
Ambient occlusion	The example in RendererFeatures/AmbientOcclusion uses a Renderer Feature to add screen space ambient occlusion (SSAO) to URP. See the SSAO_Renderer asset for an example of how to set up this effect.
Blit to RTHandle	This example describes the operation of blitting a camera color texture to an output texture, and setting the output texture as a global property. The shaders in the Scene use the global texture. Refer to the page Blit Camera color texture to RTHandle to read the example description.
Depth Blit	This sample uses a custom renderer feature to copy or render the depth texture to an RTHandle and then perform a full screen blit to screen to achieve the fading effect.
Distort Tunnel	This example describes the blit operation involving multiple RTHandle textures and a custom shader effect. Refer to the page Blit multiple RTHandle textures to read the example description.
Glitch effect	The example in RendererFeatures/GlitchEffect uses the Render Objects Render Feature and the Scene Color Shader Graph node to draw some GameObjects with a glitchy effect. See the Glitch_Renderer asset for an example of how to set up this effect.
Keep frame	The example in RendererFeatures/KeepFrame uses a custom Renderer Feature to preserve frame color between frames. The example uses this to create a swirl effect from a simple particle system. Note: The effect is only visible in Play Mode.
Occlusion effect	The example in RendererFeatures/OcclusionEffect uses the Render Objects Renderer Feature to draw occluded geometry. The example achieves this effect without any code and sets everything up in the OcclusionEffect_Renderer asset.
Trail effect	The example in RendererFeatures/TrailEffect uses the Renderer Feature from the Keep frame example on an additional camera to create a trail map. To do this, the additional camera draws depth to a RenderTexture. The Sand_Graph shader samples the map and displaces vertices on the ground.

Shaders

The URP Package Samples/Shaders folder contains examples for shaders. The following table describes each shader example in this folder.

Example	Description
Lit	The example in Shaders/Lit demonstrates how different properties of the Lit shader affect the surface of some geometry. You can use the materials and textures as guidelines on how to set up materials in URP.
