This set of assets was originally created for a PBR scene in Unreal Engine and has been re-edited in Blender. 

Therefore, all buildings and ground surfaces are modular, allowing users to customize new architectural styles, such as height, width, road extensions, and so forth.

The buildings and roads have been collapsed for easier management, but users can separate them if needed for further editing. 

Note that the modular walls have been closed on the sides to prevent light leaks, so users should avoid welding vertices by selecting the entire model.

The indoor effects for the windows utilize seven HDR images, and users can achieve a spatially aware effect using Parallax shaders. 

The FBX files, each with their original positions reset to zero, are included. These FBX files will be very helpful if users need to use them in a game engine.

The texture detail is concentrated on buildings and props near the roadway, with a texel density of approximately 512 pixels/m, while rooftop components have a density of roughly 256.
