You can achieve great detail in no time with MoI but if you dont use curves too often you may try other tools. As an example with curves, the image attached was made with MoI and Modo 701. You should look at this blog for a really great workflow: alexhogrefe.com
@Michael yep I know but it's ok it's not top secret stuff, thanks by the way :) It's really cool to work with MoI on this, will do a topic when finished !
@Pilou I made fake walls for the internals so it's not empty and you got shadows on walls coming from the windows opening on different camera angles.
