KitBash3D has released its DieselPunk environment kit—normally priced at US $245—for free download via Epic Games’ Fab marketplace. The offer runs until 18 November 2025. The kit targets artists building cinematic-quality, retro-futuristic environments in Unreal Engine 5, and is described by the studio as a “high-poly asset collection intended for use in cinematics within UE5.”
The DieselPunk kit channels Edwardian and interwar industrial design: cathedrals and palaces meet refineries and fuel stations. The architecture is “darkly beautiful,” filled with “greasy machinery, rugged materials, and industrial spires,” according to the official KitBash3D description.
Inside the kit
The package contains 316 unique actors built from 1,395 unique meshes, totalling approximately 17.8 million polygons. Mesh collision is enabled and automatically generated, but no LODs are included. There are 90 materials and 637 textures, all at 4K resolution. Texture and mesh quality clearly target cinematic or offline rendering rather than performance-constrained realtime scenes.
Formats provided include FBX and OBJ (on kitbash3d.com), and the Unreal build supports UE 4.26–4.27 and UE 5.0–5.4. Supported platforms are Windows, macOS, Linux, PS4, and Xbox One. The DieselPunk release date for this update is 8 November 2025; distribution is via the Fab marketplace as an “Asset Package.”
World-building details
The kit’s scope covers both civic and industrial architecture. Included are hotels, palaces, distilleries, apartments, mansions, towers, oil derricks, fuel stations, factories, pubs, stores, trams, bridges, storage tanks, walkways and chimneys. KitBash3D describes it as ideal for “retrofuturistic dystopias or grungy post-modern noir,” designed to help artists “make cohesive fuel-powered worlds.”
Licensing and restrictions
The Fab release uses the Fab Standard Licence, which allows both personal and commercial use across engines and tools, within Fab’s terms.
By contrast, KitBash3D’s own “free asset” policy states that assets downloaded via its Cargo app are for personal use only, whereas kits obtained directly from kitbash3d.com can be used commercially. Because DieselPunk is distributed through Fab, users should confirm commercial rights under Fab’s EULA before production use.
Technical notes for production artists
The assets are high-poly, built for cinematic fidelity. Artists targeting realtime or VR projects should expect to retopologise or create custom LODs. The automatic collision setup is adequate for blockouts, but may require manual refinement for gameplay environments.
Since materials are 4K, expect heavy texture memory use; production teams should test streaming and compression settings within Unreal Engine.
Why it matters
For concept, film, and cinematic environment work, this kit provides a time-saving foundation of consistent industrial architecture. The cohesive design language can accelerate set-dressing, look-dev and lighting passes for any diesel-era or noir-futuristic aesthetic.
Reminder
As always, test all assets in your pipeline before relying on them in production. Confirm file format compatibility, check materials and UVs, and validate licence terms before commercial deployment.
