Advanced texture artist from WB Games Montreal posted a breakdown os his Victorian office scene. For mid-poly props creation, he worked in Autodesk Maya, textures were made with Substance tools. The lighting and rendering steps were completed in Marmoset.
As for the floors, walls, and ceiling, Jonathan used simple plans with tessellation and UV information. He didn’t rely on modeling for this scene, instead focused on displacement with height maps.
