auditorium seating 3d model

Create a small realistic auditorium interior environment for a public speaking simulator. The environment should include walls on the left and right sides, a back wall, and a full ceiling roof with simple ceiling lights. Inside the room place 3 rows of auditorium seating facing a stage direction. Each row should have about 4–5 seats, totaling around 10–15 seats. The seating floor should be stepped so the first row is lowest, second row slightly higher, and third row higher like a small theater layout. Add a central staircase aisle between the seats similar to real auditoriums. The seats should look like modern auditorium chairs with armrests and dark fabric. The room should feel like a small conference auditorium with realistic materials. No people or characters. Fully modeled environment, game-ready asset, clean geometry, no grayboxing.
