# Instructions for GLTF PBR Shader

* Metallic Shader 

  Use this shader when the material is metallic.

* Rendering Mode: opaque/culling/blending
* Base Color: diffuse color
* Apply Vertex Colors: Whether to receive the vertex color in the model
* Metal Rough: Metal roughness texture. The G and B channels of the texture represent: roughness and metalness respectively. Note that sRGB is not ticked for this texture.

* Metallic: metallic degree. The final effect will be multiplied by the B value in the Metal Rough.
* Roughness: roughness. its final effect will be multiplied by the G value in the Metal Rough.
* Normal Map: note that the Texture Type in the unity property of this map is Default (do not select Normal Map), and do not check the sRGB option, as shown below:

* Occlusion: AO map
* Emissive: Self-illumination map/color
* Non-metallic Shader

  Use this shader when the material is not metallic.
