Hi Marco,

o.k. in understand! :-) To speed up your rendering workflow, you should try a demo a Marmorset Toolbag!:-)

This little guy from 3DCoat with pbr materials (metalness/glossy) took about 1 or 2 seconds to write
to my hard disk, of my 10 year old iMac. Original resolution was 1920x1080 pixels. :-)
