+# Scriptable Render Pipeline
+![](https://blogs.unity3d.com/wp-content/uploads/2018/01/image5_rs.png)
+## What is the Scriptable Render Pipeline (SRP)
+
+The SRP is a new Unity feature that has been designed to give artists and developers full control over the Unity rendering pipeline, giving them the tools they need to create modern, high-fidelity graphics in Unity. 
+SRP allows developers to write C# scripts to control the way Unity renders each frame. By exposing the Unity rendering pipeline to C#, Unity becomes less of a “black box” as developers can see and control exactly what happens during the rendering process. 
+
+Developers can use the two built-in pipelines that are provided as part of SRP (the Lightweight Pipeline and the High-Definition Rendering Pipeline(HDRP)), they can develop their own pipelines from scratch or they can modify the provided pipelines to adapt them to their own requirements. 
+
+Documentation is subject to change and may be incomplete.

+
+The High Definition Render Pipeline (HDRP) is a high-fidelity Scriptable Render Pipeline built by Unity to target modern (Compute Shader compatible) platforms. 
+
+The HDRP utilizes Physically-Based Lighting techniques, linear lighting, HDR lighting and a configurable hybrid Tile/Cluster deferred/Forward lighting architecture and gives you the tools you need to create games, technical demos, animations and more to a high graphical standard. 
+
+NOTE: Projects made using HDRP are not compatible with the Lightweight Render Pipeline. You must decide which render pipeline your project will use before starting development as HDRP features are not cross-compatible between HDRP and Lightweight. 
+
+This section contains the information you need to begin creating applications using HDRP; including information on Lighting, Materials and Shaders, Cameras, debugging and information for advanced users.
+
+HRDP is only supported on the following platforms: 
+
+__Note: HDRP will only work on the following platforms if the device used supports Compute Shaders. I.e: HDRP will only work on iOS if the iPhone model used supports Compute Shaders.__
+
+* Windows and Windows Store, with DirectX 11 or DirectX 12 and Shader Model 5.0
+* macOS and iOS using Metal graphics
+* Android, Linux and Windows platforms with Vulkan
+* Modern consoles (Sony PS4 and Microsoft Xbox One)
+
+__HDRP does not support OpenGL or OpenGL ES devices.__

ScriptableRenderPipeline/LightweightPipeline/Documentation/GettingStarted.md

+# Lightweight Pipeline
+
+The Lightweight Pipeline is a Scriptable Render Pipeline available with Unity 2018.1. The LT pipe performs a single-pass forward rendering with light culling per-object with the advantage that all lights are shaded in a single pass. Compared to the vanilla unity forward rendering, which performs and additional pass per pixel light, using the LT pipeline will result in less draw calls at the expense of slightly extra shader complexity.
+
+The pipeline supports at most 8 lights per-object and only supports a subset of vanilla Unity  rendering features. A feature comparison table of Lightweight Pipeline vs stock Unity pipeline can be found [here](https://docs.google.com/document/d/1MgoycUhS9xQKXxbTy1yHt7OCByI10rds3TyRBCSlFmg/).
+
+## Lightweight Sample Project
+
+We are providing a Lightweight Pipeline sample project that can be downloaded [here](https://drive.google.com/file/d/1i0GlWYO0SRwauqu3U2rKoUAPO8BOFXw8/). The project is already setup to render properly Lightweight Pipeline so you can easily experiment developing with the Lightweight Pipeline workflow. It comes with a modified nightmares sample scene.

+
+## How to use Lightweight Pipeline
+
+The Lightweight Pipeline does not work with the Unity stock lit shaders. We have developed a new set of Standard shaders that are located under Lightweight Pipeline group in the material’s shader selection dropdown.

+Lightweight Pipeline shaders
+
+
+**Standard (Physically Based):** Single shader with both Metallic and Specular workflows. Light model similar and upgradable from stock Unity standard shaders. BRDF: Lambertian Diffuse + Simplified Cook Torrance (GGX, Simplified KSK and Schlick) Specular
+
+**Standard (Simple Lighting): **Replaces the legacy mobile/lit shaders. It performs a non-energy conserving Blinn-Phong shading. Should be used for games that target devices with very limited bandwidth and that therefore cannot use Physically Based Shading.
+
+**Standard Terrain:** Same as Unity’s stock terrain shader. **(WIP)**
+
+**Standard Unlit: **Unlit shader with the option to sample GI. This replaces Unity’s stock unlit shaders. 
+
+**Particles: **Standard and Standard Unlit particles for lightweight pipeline. Same as Unity’s stock standard particles shaders with the exception of Distortion effect. **(WIP)**
+
+Additionally, all Unity’s unlit stock shaders work with Lightweight Pipeline. That means you can use legacy particles, UI, skybox, and sprite shaders with the pipeline with no additional setup.
+
+When the Lightweight Pipeline is set as the active rendering pipeline all game objects will be created with the correct shaders. This is achieved because the pipeline overrides the default materials in the engine. 
+
+The Lightweight Pipeline also provide material upgraders to upgrade Unity’s stock lit shaders to Lightweight ones. In order to upgrade materials go to *Edit -> Render Pipeline -> Upgrade -> Lightweight.** *Check Upgradable Shaders section below to see what unity stock shaders can be upgraded to Lightweight.
+
+1. **Upgrade Project Materials:** upgrades all materials in the Asset folder to Lightweight materials.
+
+2. **Upgrade Selected Materials **upgrade all currently selected materials to Lightweight materials.

+## Lightweight Pipeline Asset
+
+The pipeline asset controls the global rendering quality settings and is responsible for creating the pipeline instance. The pipeline instance contains intermediate resources and the render loop implementation.

+
+You can create multiple pipeline assets containing different quality levels. Assets can be set by either manually selecting a pipeline asset in Graphics Settings or by setting the *GraphicsSettings.renderPipelineAsset* property.
+
+
+
+## Creating a new project or using the pipeline with an existing one
+
+Lightweight Pipeline depends on the SRP and Post Processing packages. The packages are downloaded by the Package Manager. Currently, there’s no UI in Unity to download the packages. The packages dependencies have to defined explicitly in a manifest.json file that is located in the UnityPackageManager folder. 
+
+
+1. Copy the following [manifest.json](https://gist.github.com/phi-lira/8ada999bc71131e4a3ff4e26c935b07f) file to the project’s UnityPackageManager folder. Upon startup or refresh, Unity will download and import the Lightweight Pipeline package and its dependencies. 
+
+2. Set the project to linear color space in Player Settings
+
+3. Create a pipeline asset in *Asset -> Create -> Render Pipeline -> Lightweight -> Pipeline Asset*
+
+4. Set the pipeline asset in Graphics Settings

+## Q&A
+
+**What is scriptable render pipeline (SRP)?**
+
+SRP allow developers to write how Unity renders a frame in C#. We will release two builtin render pipelines with Unity: Lightweight Pipeline and HD Pipeline. This allows us to develop each pipeline focused on a set of target platforms, speeding up the development type. By exposing the rendering pipelines to C# we also make Unity less of a black box as one can see what is explicitly happening in the rendering. Developers can use the builtin pipelines we are providing, develop their own pipeline from scratch or even modify the ones we provide to adapt to their game specific requirements.
+
+**How does Lightweight Pipeline compare to Unity builtin pipelines?**
+
+[Here’s a feature comparison table](https://docs.google.com/document/d/1MgoycUhS9xQKXxbTy1yHt7OCByI10rds3TyRBCSlFmg/)
+
+**Who should use Lightweight Pipeline?**
+
+Developers targeting a broad range of mobile platforms, VR and that develop games with limited realtime light capabilities.
+
+**What's the development status of Lightweight Pipeline?**
+
+We are undergoing QA and optimization. Rendering quality and performance is to be improved over the next weeks.
+
+**Where’s the Lightweight Pipeline source? How can I modify it or create my own pipeline?**
+
+Lightweight Pipeline resources are embedded in a package that gets downloaded by the Unity Package Manager. The package contents lie inside an internal Unity cache and they are not visible in the project folder. If you want to have access to Lightweight Pipeline source take a look at the Scriptable Rende Pipeline [github page](https://github.com/Unity-Technologies/ScriptableRenderPipeline/issues). We are working on the API and shader documentation at the moment.
+
+**I found an issue. How should I report it?**
+
+You can report any issues found in our[ github page.](https://github.com/Unity-Technologies/ScriptableRenderPipeline/issues)
