Overview

Physically based rendering (PBR) shaders for Unity derived from Filament shaders. More beautiful and accurate rendering than Unity Standard shaders.

Map Channel

Basically same as Unity HDRP mapping

Albedo

Mask Map

Detail Map

Height Map

Gene Lit Shaders provides more accurate parallax than Standard Shader by sampling a height map twice.

A height map and a directional light can be used to create a pseudo-shadow effect.(Height Map Shadow)
