night of the reading dead

So I've not made any metals until now really in unreal 4, was going over some documentation about pbr stuff and noticed that theres a key difference between unreal 4 and marmo (which is where i started) that the specular levels are pulled from the albedo texture in unreal 4, opposed to a colour specular map in marmo.

So I plugged the steels spec into the albedo and rejigged a few things around, looks more.. colourful now. huzzah for reading!

oh and a rust texture.

This is an awesome document for anybody who cares about pbr, or reads my blog and wants to read something worthwhile for a change.
