It comes down to the following:
- all materials (accept glass, I used fake glass from Andrew) are neutral grey (50%) --> layer proportions > Override
- Place the lights in the order of primary, secundary and fill lights (my primary is hdri with portals at windows, secondary the spots in the ceiling and above table, fill lights weren’t necessary)
- play with the values of these lights seperate untill it looks realistic, then all lights together
- Apply the materials you wan’t, and it’ll look really realistic.
Hope this will help you
