Dieselopolis: Dystopian Megastructure

Dieselopolis: Dystopian MegaStructure is a modular 3D environment pack and procedural building toolkit designed for creating dense industrial, dieselpunk, cyber-dystopian, and megastructure environments in Unity, with support for HDRP, URP, and the Standard Built-in Render Pipeline.
The pack includes 156 meshes covering modular architecture, residential and industrial structures, structural frames, exterior pipes, props, decals, holographic elements, and environmental details.
Dieselopolis also includes a collection of custom editor and runtime tools designed to reduce repetitive environment-building tasks and speed up large-scale scene creation.
