The package samples that URP provides are:
For information about installing package samples, refer to Import a package sample in URP.
URP Package Samples is a package sample for the Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (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 sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary, 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.
The URP Package Samples/CameraStacking folder contains examples for Camera Stacking. The following table describes each CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary 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-processingA process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info post processing, postprocessing, postprocessSee in Glossary on world-space and screen-space camera UI. |
| 3D skyboxA special type of Material used to represent skies. Usually six-sided. More info See in Glossary |
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 pixelsThe smallest unit in a computer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More infoSee in Glossary 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. |
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. |
The URP Package Samples/LensFlares folder contains lens flareA component that simulates the effect of lights refracting inside a camera lens. Use a Lens Flare to represent very bright lights or add atmosphere to your scene. More info
See in Glossary 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. |
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 probesA rendering component that captures a spherical view of its surroundings in all directions, rather like a camera. The captured image is then stored as a Cubemap that can be used by objects with reflective materials. More infoSee in Glossary to create reflection maps for a reflective sphere GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info See in Glossary. This sample shows how the Probe Blending and Box Projection settings can change the reflection within a scene that uses reflection probes. |
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 occlusionA method to approximate how much ambient light (light not coming from a specific direction) can hit a point on a surface. See in Glossary |
The example in RendererFeatures/AmbientOcclusion uses a Renderer Feature to add screen space ambient occlusion (SSAO) to URP. For an example of how to set up this effect, refer to the SSAO_Renderer asset. |
| 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. For an example of how to set up this effect, refer to the Glitch_Renderer asset. |
| 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. |
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. |
After you install the Render Graph Samples, the URPRenderGraphSamples folder contains examples of Scriptable Renderer Features that use the render graph system.
To use an example, follow these steps:
For more information, refer to Add a Renderer Feature to a URP Renderer.
To get more information about each sample, use the Render Graph Viewer to visualize the sequence of render passes. Some examples are for API demonstrative purposes and don’t generate a visible output in the Game or Scene viewAn interactive view into the world you are creating. You use the Scene View to select and position scenery, characters, cameras, lights, and all other types of Game Object. More info
See in Glossary, but you can use the Frame Debugger to see their output.
| Example | Description |
|---|---|
| BlitA shorthand term for “bit block transfer”. A blit operation is the process of transferring blocks of data from one place in memory to another. See in Glossary |
Copies the active color texture to a new texture. |
| Blit w. FrameData | Demonstrates how Blit operations can be handled using frameData with multiple ScriptableRenderPasses. |
| BlitWithMaterial | Blits the active CameraColor to a new texture. Shows how to perform a blit with material and use ResourceData to avoid another blit back to the active color target. This example is for API demonstrative purposes. |
| Compute | Shows how a compute shader can be used together with RenderGraph. |
| Culling | Renders the scene geometry associated with a specific layer using the culling results, for API demonstrative purposes. |
| FramebufferFetch | Copies the target of the previous pass to a new texture using a custom material and framebuffer fetch. This example is for API demonstrative purposes. |
| GBufferVisualization | Uses the gBuffer components in a RenderPass when they are not global. |
| GlobalGBuffers | Sets the gBuffer components as globals (it renders nothing itself). Adding this feature to the scriptable renderer allows subsequent passes to access the gBuffers as globals. |
| MRT | Demonstrates how to use Multiple Render Targets (MRT) in RenderGraph with URP. Useful when more than 4 channels of data (a single RGBA texture) need to be written by a pass. |
| OutputTexture | Uses RenderGraph to output a specific texture in URP, shows how to attach a texture by name to a material, and demonstrates how two render passes can be merged if executed in the correct order. |
| RendererList | Clears the current active color texture, then renders the scene geometry associated with a layer maskA value defining which layers to include or exclude from an operation, such as rendering, collision or your own code. More info See in Glossary. |
| TextureReference w. FrameData | Creates a texture reference ContextItem in frameData to hold a reference used by future passes. This avoids additional blit operations copying back and forth to the camera’s color attachment. |
| UnsafePass | Copies the active color texture to a new texture and then downsamples the source texture twice. This example is for API demonstrative purposes. |
