TIL Shader Keywords

A short month begins

So a few months ago, I basically verified for myself that the Godot Engine works on Chromebooks via Linux. There's also a fascinating tool called Material Maker which is built off of Godot and (you guessed it!) it too works on Chromebooks via Linux.

With this tool, it's possible to export Unity Materials. I took a peek at the exported files and the only thing that stood out was the .mat file. I opened it and it's a YAML file that describes the material and its properties.

%YAML 1.1
%TAG !u!,2011:
--- !u!21 &2100000
  serializedVersion: 6
  m_ObjectHideFlags: 0
  m_CorrespondingSourceObject: {fileID: 0}
  m_PrefabInstance: {fileID: 0}
  m_PrefabAsset: {fileID: 0}
  m_Name: test
  m_Shader: {fileID: 46, guid: 0000000000000000f000000000000000, type: 0}
  m_LightmapFlags: 4

The Shader Keywords caught my eye.
Uber Shaders are a shading method I've seen on prior projects; this is where your project has one shader to rule them all but this shader has many "variants" that are generated based on the Shader Keywords. In Unity, the idea is that you can have many materials that use just one shader asset but can look different because of the shader variants.

cool! I transferred materials from blender 3d to Unity in much the same way
