Cityscape Pro is a plugin from SIMPOLIUM that builds city environments inside 3ds Max. It uses a surface geometry as the base for all calculations: you click the Pick Surface button, select your surface, and once Curbed Areas are generated on top of it, the exposed part of the surface turns into a road.
The plugin ships with a Material Library of over 70 V-Ray and Corona presets. These materials apply to Cityscape elements as well as any other object in the scene. Generation runs through an interactive Generate button that turns blue and flashes when it detects changes, and turns red when it detects problems with the input elements.
For the base surface, clean uniform geometry works best, with quad polygons recommended and a low polycount for faster calculation times. Cityscape Pro uses a custom installer rather than the standard App Store installer. This is version 1.5.1, updated in August 2022.
