Yes, exactly. CIE must be an unique tool, not a PS replacement.
That's why I suggest you to think seriously at Motiva Colimo features.
I have read in this forum, some guy who make 200.000 rendering for a catalogue.
In Italy, a lot of people make a technical catalogues with different material.
No one renderer in the World has the same tool like Colimo.
The possibility to change color, textures, UVW in post it something invaluable. =)
