A customized forward+ render pipeline for Unity

SRP

Description

A customized forward+ render pipeline for Unity

Planned Features

1. Supports forward+ render path (Implemented)
2. Supports tile-based light culling with transparent objects (Implemented - Both dither transparent & transparent)
3. Supports realtime directional light / spot light / point light shadows (Implemented - Both hard shadows & soft shadows)
4. Supports cascaded shadowmap for directional light (Implemented)
5. Supports volumetric lighting
6. Supports Mie-scattering skylight
7. Supoorts screen space decals
8. Supports global illumination
9. Supports stochastic screen space reflection
10. Supports MSAA / FXAA / SMAA / TAA

Possible Features

1. Supports GPU culling
2. Supports nonphotorealistic render pipeline
3. Supports in-pipeline GPU grass
4. Supports in-pipeline post-processing stack
5. Supports groundtruth ambient occulsion

Graphic API

1. DX11+ on Windows
2. Metal on Mac
3. OpenGL 4.5+ on Linux

PS: Graphic APIs that support Compute Shaders.

srp's Issues

SAMPLE_TEXTURE2D_ARRAY_SHADOW cannot map expression to ps_4_0 instruction on DX12

Another problem is why the editor is blurred?There don't have a post pocessing gameobject.
My enviroment is Windows10,gtx1650.

err in editor
