ToyRenderPipeline

Custom Render Pipeline with Unity SRP（Scriptable Render Pipeline）including various of popular graphic features

Gallery

Physical Based Rendering（PBR）and Image Based Lighting（IBL）：

Cascaded Shadow Mapping（CSM）and Soft Shadow（PCSS）：

Cluster Based Light：

GPU Based（frustum& Hi-Z occlusion）Culling using compute shader：

Features

• Deferred Shadings Pipeline
• Physical Based Rendering（PBR，direct light）
• Image Based Lighting（IBL，ambient light）
• glTF Material support
• Cascaded Shadow Mapping（CSM）
• PCSS soft shadow
• Cluster Based Deferred Lighting
• GPU Based Culling（Frustum & Occlusion）

Environment

• Unity 2021.2，win 11，DX 11
• UniGLTF package（alternative，you can config material in Unity Inspector）
• MRT supporting GPU

Usage

• Menu Create > RenderPipeline > ToyRenderPipeline，create a pipeline asset
• Menu Edit > Project Settings > Graphics，select the custom pipeline
• Bind ToyRP/gbuffer shader to all materials

Compare With Unity

Using some tricks trying to align the rendering result to Unity Build-in Pipeline，left column is IBL effect，while right is direction light
