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
