Free Fab Assets Until October 20: 3 Unreal Engine Packs You Should Claim Now
Quick Summary
Fab is offering three Unreal Engine assets for free until October 20. One is an AI navigation plugin, one is a full post-apocalyptic bridge environment, and one is a cozy stylized farm pack. If you build with Unreal, all three are worth adding to your library before the deadline.
The short version:
- AdaptivePathfindingSystem: AI Navigation Plugin is for developers who want AI agents to move along curved or wavy paths instead of rigid straight lines.
- Ready Map Vol 2 – Bridge Environment / Nature is a complete environment pack with 342 meshes, 128 prefabs and an auto-material landscape.
- Stylized Harvest Farm Environment is a lightweight low-poly pack for farming games, cozy sims and stylized RPGs.
Free assets are only worth it if they fit your project, so here is what each one offers and who should skip it.
Time remaining for the offer…
1. AdaptivePathfindingSystem: AI Navigation Plugin
Best for: AI programmers, RTS and crowd-based games, anyone tired of robotic NPC movement.
APS (Adaptive Pathfinding System) works on top of Unreal’s own Recast NavMesh. You keep your existing AI MoveTo or Behavior Tree Move To nodes, and the plugin reshapes the route the agent takes. No engine source changes are needed.
What you get:
- Arc Strength controls the direction and amount of the bend in a path.
- Midpoint Mode switches between a smooth curve and a wavy, hump-style path.
- Lane Offset adjusts lateral spacing around turns, which helps groups of agents avoid stacking on one line.
- Support for slopes, stairs and elevation changes on the NavMesh.
- Corridor options for Unreal’s Detour Crowd.
- Debug tools: path lines, points, navigation logs and a runtime overlay.
- Documentation with five Blueprint examples, including waypoint patrols and AI-state profiles.
Compatibility: Unreal Engine 4.27 and 5.0–5.8 (version 2.06).
Rating on Fab: 4.5 out of 5 from 24 ratings.
Who should skip it: If your game only needs agents to reach point B by the shortest route, default navigation is enough.

2. Ready Map Vol 2 – Bridge Environment / Nature
Best for: Environment artists, level designers, and solo devs who need a finished-looking scene quickly.
This pack from Six Sides Studios is built around bridges, with road props, vegetation and a landscape material included, so you can assemble a full composition without hunting for extra assets.
What’s inside:
- 342 unique meshes
- 128 prefabs (122 of them Blueprint prefabs)
- 16 master materials and 82 material instances
- 3 dynamic Blueprints for connecting wires between posts
- 1 vehicle
- An auto-material landscape with procedural vegetation
- Lumen compatibility
- Billboard LODs for all trees and six grass types
- Collision on most meshes
The listing also links to a playable demo on Itch.io and a full-map overview video, so you can see the quality before you download anything.
Good to know:
- Some landscape items use Runtime Virtual Textures. Turn on Enable virtual texture support in Project Settings, or disable it in the material if you don’t want it.
- The listing marks “Allows usage with AI” as No. If you use AI tools in your pipeline, read the license terms first.
Rating on Fab: 4.4 out of 5 from 13 ratings.

3. Stylized Harvest Farm Environment
Best for: Farming sims, cozy games, stylized RPGs, mobile projects and game jam prototypes.
Emberlight Creations built this pack around warm colors and a consistent low-poly look. It covers fields, buildings, props and natural elements, with tags pointing to barns, windmills, scarecrows and wheat.
Why it’s useful:
- Lightweight, game-ready meshes
- Suitable for mobile, PC and stylized projects
- Most props use only diffuse textures, often with normals and roughness
The pack is a good base for prototyping, and it is easy to restyle later because the textures are simple.
Rating on Fab: 5.0 out of 5, but from only 6 ratings. That is a good sign, though a small sample.

Frequently Asked Questions
Are these Fab assets really free?
Yes, until October 20 according to the current promotion. After that, they return to their regular prices.
Do I need Unreal Engine 5 for all of them?
Not necessarily. The pathfinding plugin lists support for UE 4.27 and 5.0–5.8. For the two environment packs, check the supported versions on each listing before adding them to a project.
Can I use these in a commercial game?
That depends on the license you select on the listing. Open the license terms and read them before you ship anything.
Are any of these assets AI-generated?
All three listings say “Generated with AI: No.” Only the farm pack and the pathfinding plugin allow usage with AI. Ready Map Vol 2 does not.
Final Thoughts
This is a well-rounded batch: a tool for smarter AI movement, a big environment kit, and a lightweight stylized pack. You don’t have to use all three, but claiming them costs nothing and the deadline is October 20.
