StarRailNPRShader

Fan-made shaders for Unity URP attempting to replicate the shading of Honkai: Star Rail. The shaders are not 100% accurate because this project is not a reverse engineering - what I do is to replicate the in-game looks to the best of my ability.

Requirements

• Unity 2022.3 (Recommended).
• Universal RP 14.0 or higher.
• My ShaderUtilsForSRP package.
• Newtonsoft Json package 3.2.1 or higher (Optional).

Newtonsoft Json is used by a custom editor util called Game Material Inspector which can help us read Material JSON files ripped by a certain tool. To enable that tool, add the scripting define symbol PACKAGE_NEWTONSOFT_JSON in player settings after importing Newtonsoft Json package.

Extra features

Asset preprocess:

• Automatically smooth the normals of character models and store them into tangents. The file name of the model must match pattern ^Avatar_.+_00$.
• Automatically process textures (if you haven't changed the file names after ripping them).

PostProcessing:

• Custom bloom using the method shared by Jack He in Unite 2018.
• Custom ACES tonemapping.

Guide

• Use linear color space instead of gamma.
• HDR should be enabled.
• Depth priming must be disabled.
• Depth texture must be enabled and generated by a depth prepass.
• Rendering path must be forward currently.
• Renderer Feature StarRailForward must be added to the renderer.
