Many mini-custom-SRPs showing how to achieve different things when creating your own SRP. Only SRP Core package is needed.
CustomSRP
A new SRP from scratch
Unity version : 2022.2+ 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 |
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 |
