CustomSRP

A new SRP from scratch

Unity version : 2023.1.0b17+ Checkout to branches for older versions

Tested with : Win DX11

Scene	Image	Description
SRP0101_Basic		Super basic SRP that renders unlit material objects
SRP0102_AssetSettings		Let the SRP Asset to pass some custom variables
SRP0103_CustomGUI		Have a proper interface for the SRP Asset
SRP0201_FrustumCulling		Frustum culling always work. This is a test scene to verify the culling results
SRP0202_OcclusionCulling		Baked Occlusion Culling always work also. This is just a test scene to verify it
SRP0301_Batching		Use Static Batching, Dynamic Batching, GPU Instancing and SRP Batcher
SRP0401_NoSpecificPass		To draw the shaders that do not have a tag, e.g. default Unlit shaders
SRP0402_Multipass		In SRP we need to specify the pass names, so no more infinite pass. But we can specify the orders of passes
SRP0403_Compute		Use compute shader to achieve simple edge detection
SRP0404_DrawCommands		using CommandBuffer functions (DrawMeshInstancedIndirect)
SRP0405_Callback		Make your custom callback function so that you can insert extra rendering code with other scripts
SRP0406_ShaderDebugPrint		Print pixel values from shader to Console
SRP0501_SoftParticle		Setup CameraDepthTexture to achieve soft-particle effect
SRP0502_Distortion		No more grab pass but we can implement our own
SRP0101_Fog		Use Fog on Lighting Settings
SRP0601_RealtimeLights		Directional / Point / Spot lights and setup PerObject light data
SRP0602_BakedLights		Baked Lightmap / Reflection Probe / Light Probes and setup PerObject data for them
SRP0603_RealtimeShadowDirectional		Directional light realtime shadow
SRP0701_HDR_MSAA		Use HDR and MSAA
SRP0701_HDR_MSAA_RTHandle		Same as above, but using RTHandle instead of RenderTargetIdentifier
SRP0701_Stencil		In order to use stencil, we need the render target having at least 24bit depth. This case we use the same pipeline with 0701
SRP0702_Postprocessing		This shows you how to use Postprocessing Stack with SRP (transparent effects e.g. Bloom, Depth of Field)
SRP0703_MotionVector		Make motion blur works. Use per-object and camera motion vector
SRP0801_UGUI		Use UICamera to render UGUI, also render 3D objects and particle on UI
SRP0802_RenderPass		Use RenderPass to target multiple color attachments and read / write from / to them
SRP0802_RenderGraph		Use RenderGraph to modularize rendering passes. Use Window > Render Pipeline > Render Graph Viewer to see RT read/write status in each pass
SRP0802_RenderGraph_RasterCommandBuffer		Similar to above but using RasterCommandBuffer in RenderGraph
SRP0803_MultiRenderTarget		Use CommandBuffer.SetRenderTarget() to target multiple color surfaces
SRP0901_SceneViewFix		Make the gizmos / icons appear on scene view
SRP0902_SceneViewDrawMode		Adding custom Scene View draw modes
SRP1001_Error		Render the pink shaders on the materials that the SRP doesn't support
SRP1002_Debug		Make the Profiler records the timing for SRP performance debugging
SRP1003_DefaultShaders		Set pipeline default materials when creating new material / objects / particle / terrain etc
