01 · The Platform

UEFN and Fortnite Creative

UEFN, Unreal Editor for Fortnite, is Epic Games' tool for building and publishing islands, the experiences players enter in Fortnite. Creators can import custom assets beyond those in Fortnite Creative, such as models and textures from 3D software. For art, that means assets built to Epic's guidelines for scale, polygon counts, LODs and memory.

UEFN shares parts of its asset workflow with Unreal Engine: static mesh import follows the same FBX restrictions. Not every Unreal Engine feature or file format is available in UEFN, so each project starts from Epic's current documentation.

CONTEXT 01

Fortnite Scale and Units

Epic's guidelines set one unit to one centimeter, the Z axis as up and a grid size of 512 cm, and note that player characters in Fortnite are 192 cm tall. Normal maps use the DirectX convention. Using the project's agreed scale, pivots and grid conventions helps assets fit consistently into modular environments.

Art priority: correct scale against the 192 cm player, modular pieces that snap to the grid, consistent pivots

Agreed at the brief: which guidelines version applies, grid and kit sizes

CONTEXT 02

Polygon Budgets and LODs

Epic gives reference polygon budgets for the highest level of detail by complexity and mesh size, recommends three LODs with each level about half the polygons of the previous one, and suggests limiting collision to 10 UCX meshes or fewer. Budgets are set per asset class, so a prop is not built like a hero object.

Art priority: efficient topology, clean silhouettes, LOD-friendly UVs and one shared material across LODs

Agreed at the brief: asset classes, budgets, collision approach

CONTEXT 03

Textures, Materials and Memory

Epic recommends texture maps of 2k or smaller in power-of-two sizes, in TGA or PNG, and for Switch and mobile 512 × 512 textures with ideally one material section per mesh. UEFN tracks publishing memory separately from runtime memory usage, and an island over the publishing budget cannot be published. Custom meshes, textures and materials can contribute to these budgets, so specifications follow the project's current memory targets and the devices it supports.

Art priority: disciplined texture sizes, shared materials, trim sheets and reusable kits

Agreed at the brief: texture limits, material conventions, target devices

CONTEXT 04

One Island, Many Devices

Fortnite has a cross-platform player base, and islands run on supported UEFN platforms including mobile. Texture memory can be limited on mobile and Switch. Supporting mobile and other lower-powered devices affects the asset budgets and quality tiers agreed for the island.

Art priority: assets that hold up across targets, modular kits, controlled detail

Agreed at the brief: target platforms, shared versus per-platform assets

UEFN, Fortnite Creative and Publishing

Public documentation shows what the target looks like. Exact requirements for a project come from your team and Epic.

Unreal Editor for Fortnite

The editor where islands are built, scripted with the Verse programming language, tested and published. Custom assets are imported from 3D modeling software, Fab or Sketchfab. Supported model formats include FBX, OBJ, USD, glTF and GLB. Epic's documentation states that an import that does not meet its criteria will fail, and the editor can also report warnings for issues it detects.

Fortnite Creative

The Fortnite Creative toolset and asset library are the baseline that UEFN goes beyond. Epic notes that UEFN and Fortnite Creative do not yet support all file formats.

Publishing

Islands are published and managed through Epic's Creator Portal. Content rules, ratings and any monetization terms come from Epic and apply to the island owner.

Your team defines the production pipeline. Together, we agree on asset specifications covering scale, geometry budgets, LODs, collision, textures, file formats and naming. We produce the agreed assets and organize the source files for handoff.

Epic's Reference Polygon Budgets
(LOD0 Maximum)

From Epic's Fortnite-ready asset guidelines, which describe them as a rough estimate for reference and recommend testing assets by importing them into UEFN. Guidelines change over time, so your team confirms the current figures.

Complexity	Small mesh	Medium mesh	Large mesh
Simple	400	900	2,500
Medium	700	2,000	6,000
Complex	1,200	4,000	9,000

05 · How We Work

Direct or Part of Your Team

Choose the model for where you are – it can change as the project does.

Direct Engagement

You provide an agreed asset list – props, environments, weapons or vehicles – and our art director and project manager coordinate the production and delivery of those assets through the approved review stages.

Team Extension

Our artists work within your pipeline and under your art direction – you run the process, we add the capacity and the skill.

Guidelines First

Before production we agree the specification sheet described above, and production and handoff follow it. Island building, scripting and publishing stay with your team.

FAQ's: UEFN Game Art

What makes art for UEFN different?

Epic publishes guidelines for UEFN assets, including scale in centimeters, polygon budgets by asset class, LODs and texture limits. Islands also run on several platforms, so the weakest target shapes the budgets. Your team confirms the current rules.

Is UEFN the same as Unreal Engine?

No. UEFN shares parts of Unreal Engine's asset workflow, such as the FBX restrictions for static meshes, but not every Unreal Engine feature or file format is available. Assets are built to Epic's current UEFN guidelines.

Do you have a UEFN project in your portfolio?

Not yet. We have not published a project delivered for UEFN or Fortnite. The closest evidence is our work on Unreal Engine games, and a UEFN version of any of them is not documented.

Do you build islands or write Verse?

No. We produce game art, such as props, environments, weapons, vehicles and concept art, and your team handles island building, Verse scripting and publishing. We deliver assets to your specification sheet and organize files for handoff.

Can Unreal Engine assets be reused in UEFN?

They can be a starting point, but Epic's budgets, scale rules, LOD recommendations and import criteria may call for adjusted assets, and imports that do not meet the criteria can fail. We agree which assets are shared at the brief.

How do I get an estimate for a UEFN project?

Email sales@nastyrodent.com or use the form on this page. Include your asset list, art direction and target platforms. A spreadsheet of asset names is enough to begin; we reply with questions or a first estimate in 1–2 business days.
