This set was modelled in 3ds max 2020. We used Vray for the materials and lights. Photoshop was used for Post-production. CAD models were supplied from the customer which were prep'ed and imported into 3ds max. This process has been greatly improved over the past couple of years. Way back when, NURBS files in 3ds max was a nightmare. Now it's a breeze. The days of exploding models are behind us :)
