PBS_Metallic Shaders Exhibit Channel Packing Inconsistency

[Epimonster]

Describe the bug?

Only PBS_Triplanar_Metallic and PBS_Metallic sample ambient occlusion from the green channel, all the other variants sample it from the red channel instead.

To Reproduce

Using a packed metallic map of the following standard:

R - Metallic G - Ambient Occlusion A - Smoothness

Place it into both the occlusion and the metallicmap slots. The ambient occlsuion will only properly render on PBS_Triplanar_Metallic and PBS_Metallic and will fail to display on the other ones.

I included an example map from the Gas Station you can use.

Expected behavior

All PBS_Metallic variants and Xixie toon should sample ambient occlusion from the green channel.

For clarity's sake the following materials do not sample ambient occlusion from the green channel of the metallic map:

• PBS Color Mask Metallic
• PBS Displace Metallic
• PBS Distance Lerp Metallic
• PBS Dual Sided Metallic
• PBS Intersect Metallic
• PBS Multi UV Metallic
• PBS Rim Metallic
• PBS Slice Metallic
• PBS Stencil Metallic
• PBS Vertex Color Metallic
• PBS Lerp Metallic
• Xiexie Toon

I believe this would be implicitly covered under the shader consolidation #1577 - but seeking input from @Geenz.
