AI assets for UEFN (Fortnite Creative)

Atlas expands a theme phrase into a full point-of-interest kit — concept art, isolated landmark meshes, multi-tier LODs, and UEFN grid-aligned export, all from one line of text.

Theme to concept

An LLM expands your theme phrase into a full environment concept prompt — grid compatibility, sightlines, and silhouettes included — then renders one wide master concept image.

Four individual structures isolated on gray backgrounds: a prize stall, an arcade building, a funhouse entrance, and a ferris wheel

Structure isolation

The master concept is broken down into individual landmarks and isolated onto clean backgrounds, ready for reconstruction.

3D reconstruction

Each isolated structure reconstructs into a textured mesh with PBR materials — assembled, the set reads as one coherent kit, not five unrelated props.

LOD & grid prep

Each mesh gets multiple LOD tiers, its scale normalized to standard grid units, and its origin set to bottom-center for ground placement — exported as FBX.

Where the time goes

Stage	Manual	Atlas
Concept & structure prompts	1–2 days	a few seconds
2D concept & isolation renders	4–6 days	15–30 seconds
3D reconstruction & LOD remeshing	2–4 weeks	1–3 minutes
Total, theme to export-ready kit	3–6 weeks	2–5 minutes

Common questions

What does this workflow output?

Downloadable FBX archives per building or prop, each with PBR texture maps and multiple LOD tiers (for example 20,000 / 7,500 / 2,500 faces), plus the 2D master concept and isolated hero renders along the way.

How long does it take?

2 to 5 minutes end to end for a full point-of-interest kit — prompt expansion, concept art, isolation, and parallel 3D reconstruction with LODs.

Can I control the art style?

Yes — the current setup targets Fortnite’s saturated cartoon-realism, set in the system prompt. Editing that prompt or the theme text swaps the direction entirely — photorealistic, stylized, low-poly, dark fantasy, and more.

Which engines are supported?

Exported as FBX, scaled to UEFN’s 512cm grid with a bottom-center pivot and Z-up/Y-forward orientation, matching Epic’s own published guidance for Fortnite Creative. The same FBX output also drops into Unreal Engine, Unity, Godot, and DCC tools like Blender or Maya.
