Detailed isolated 3D city map of Boston with buildings, parks, trees and water, prepared for architectural visualization and motion graphics. Includes Blender, Cinema 4D, FBX, GLB and OBJ packages plus a turntable preview. Native geometry: 2,135,573 polygons / 1,254,869 vertices. Materials and MassGIS Spring 2025 ground imagery included. UV mapping is partial, not a fully unwrapped asset. Native Blender uses metric scene scale. OBJ and GLB use 1:100 of native Blender coordinates; multiply by 100 to restore native size. Interchange files use Y-up; native Blender is unchanged. Export triangulation and split vertices can change displayed counts. This is an approximate visualization assembled from mixed-date geographic data, not a survey model or a guarantee of current building conditions. Official Boston geometry is supplied under the source download statement’s PDDL terms. Ground imagery: MassGIS Spring 2025. Other source acknowledgements and license notes are retained in the package.
