Hi everybody! The goal here was not to have a old Loft/Studio and furnishes it, the goal was to have a new space, constructed from scratch and give old loft appearance; Some models used are from Design connected and 3dsky. My the workflow was always the same;
Created with 3Ds max and Vray
Light used was HDRI + GI, and some photometric light over the pictures in staircase.
IR + LC calculations 4 times less than the final image resolution
IR ? Preset High
LC is about 3000; Retrace threshold off (on, took along time to render)
Reinhard color mapping: 1|0.05|2.2
HDRI (0927 Wispy Clouds from Peter Guthrie)
