Yes, Pilou, I know you are a big fan of ketchup:)

That model by silvershadow is pretty amazing. That guy has a lot of free time!!

I can see that a good workflow could be

build model in MoI
export to SU
add materials
export to KT
build scene
render

Because of my arch background, I export from MoI to Cycas which (apart from being a great arch application) has a good, easy portal to povray
