Epic Games has released a free modular 3D environment pack on its Fab marketplace, aimed at users of Unreal Engine. The set contains 50 assets, all themed around a generic urban back alley. Think static meshes like trash bags, dumpsters, brick walls, aircon units, busted pallets, pipes, fences, street signs, and all the cable clutter needed to make your real-time backlot look less staged.
The pack is free to download and use in both personal and commercial projects. And yes, you can use it outside of Unreal Engine too – as long as you’re okay downloading the FBX versions manually.

Technical Details: No Nanite or Lumen Required
Unlike some asset drops, this one doesn’t lean on Unreal Engine’s newer features like Nanite or Lumen. That means the models can be used in older or lighter-weight projects. All 50 assets are static meshes – no rigging, no animation.

Textures are provided in 2K resolution, and come in standard PBR (physically based rendering) format. That covers base color, roughness, normal, and ambient occlusion maps. There’s no mention of displacement or metalness, so don’t expect hero shaders.

Each model is available in both FBX and native Unreal Engine format. If you download through the Fab plugin in Unreal Engine 5.4 or higher, it’s a straight shot into your project. If you’re still hand-loading files like it’s 2015, the FBX versions are right there in the listing.
Licensing: Free Means Free
According to the Fab listing, these assets are released under Epic’s standard End User License Agreement. That allows use in commercial and personal projects, including mods and educational work. Redistribution as a competing product is not allowed – you can use it, not resell it. No price to mention, because it’s free. Fab accounts are free, too, though registration is required.
Final Word: Junkyard-Tested, Production-Ready?
These assets are as production-friendly as they get – assuming you’re aiming for stylized grime, not photogrammetry-level fidelity. With 2K textures and basic static meshes, they’re well-suited for pre-viz, background dressing, or any realtime project that doesn’t demand Pixar-grade assets. As always, test in your current pipeline before deploying them in active productions. No one wants to debug UVs mid-delivery.
