Hi Gen, thanks for taking a look at this. I've uploaded some more photos as requested.
There is the shader tree for the mia_material_x and it's corresponding attributes in the editor.
I placed the diffuse pass in the DIFFUSE>COLOR
I places the reflection pass in REFLECTION>COLOR
and the glossy pass in the REFRACTION>GLOSSINESS (perhaps not where is should be?)

The other images are for the diffuse pass and its other parts - The Projection, the File and the Project2d

Thanks again.
