Send2Unreal Material Pathing

[TomZandt]

Is the send2unreal materials supposed to work like this? Iim having an issue sending them across without having to remake everything as its missing a few and remapping some?

I have baked my materials down to 1 texture per input in Blender:
BaseColor (diffuse)
Metallic
Specular
Roughness
Alpha
Normal

However when using send2unreal it only imports the follwoing (in the wrong slots)
Diffuse
Specular (in roughness slot)
Roughness (in metallic slot)

Is this meant to do this?

I understand if i need to remake the textures etc, but would be good to have this atleast import all the textures etc. Is there somewhere that says which slots from blender on the bsdf are importable and what they link to?

Thanks
Tom
