The file contains a congress, event, meeting and conference hall model. You can easily change the materials and colors of the products with the dropper tool. I also offer you outputs in extra formats.
The reason for the high polygon count of the file is that the seats were not reproduced with a proxy. The reason for this is to make it easier for you to align the oval structure. You can directly convert it to a proxy. There is only a seat model in the .obj file.
Number of ranges without seats: P: 4.923.085 / V: 4.229.615
Extra Formats: 3ds, fbx, stl, obj and max
