Custom shader pipeline using Unity3D SRP and HLSL

In order to gain more intuition for scripting render pipelines this project implements a custom forward render pipeline in Unity3D by using its scriptable render pipeline (SRP) and HLSL for the shaders. For some parts following the tutorial by CatLikeCoding.

Currently supports:

  • Unlit and Lit shaders
    • Opaque and transparant.
    • Texture sampling.
  • Illumination by multiple colored directional lights
    • BRDF controlled by metallic and smoothness parameters.
    • Casted shadows using light maps.
      • Support for cascaded light maps.
      • Support for varying light map resolution.
      • Clipped shadows for transparent objects.
    • Support for soft shadows using PCF.
    • Support for normal maps.
  • Global illumination
    • Support for sampling from the lightmaps generated by Unity for static objects.
    • Support for using light probes and LPPVs to approximate GI for dynamic objects.
    • Meta pass for colored GI.
  • Specular reflections
    • Support for reflections from the skybox.
    • Support for reflections from unity reflection probes.
    • Reflection sharpness affected by surface rougness.
  • Support for emmisive surfaces.
  • Support for point lights + shadows.
  • Support for spot lights (without shadows).
