This model was made using real world scale for main shapes and details.
The blend file consists of the main layer which contains meshes as group and other layers containing the meshes with modifiers preserved.
This method is really handy when modifications are needed.
The hall can be resized in a matter of minutes.
The model has clean and fairly low topology, ready for UV unwrapping and texturing.
Unfortunately due to copyright the hdri used to render the scene is not included with the model.
After purchase you’ll get my full support if needed.
