AI 3D models for Unreal Engine

Block out a level with real props instead of grey boxes, or fill a scene with set dressing. Unreal Engine 5 imports glTF and GLB files directly, materials included.

Loading model

Input image for the sci-fi helmet — Sci-fi helmet
From a FLUX.2 Klein concept image, meshed with Rodin Gen-2.
Optimised for the web; the file you download from the studio is full size.

Which format to use: GLB

Unreal Engine 5 imports .glb and .gltf through the Content Browser, drag and drop, or Import Into Level.

Formats: Unreal Engine 5 imports .gltf and .glb through the Interchange import pipeline.
How: Content Browser Import, drag and drop into the Content Browser, or File, Import Into Level.
Our output: Rodin Gen-2 at default settings: about 30,000 to 40,000 triangles with 2048 × 2048 PBR maps, a comfortable density for props.

From prompt to finished file

Make the prop
Generate the model and download the GLB.
Import it
Drag the .glb into the Content Browser and confirm the import options.
Place and light it
Drop the static mesh into your level; the PBR materials react to your lighting.

Prompts to start from

Each one opens Text to 3D with the prompt filled in. The concept image is drawn first so you can check it before meshing.

Tips for better results

Generate variations
Run the same prompt with small changes to get a set of matching props for one area.
Check scale
glTF uses metres and Unreal uses centimetres, so compare the size with the mannequin after import.
Start from concept art
Mesh the concept art you already have with Image to 3D to keep the art direction consistent.

Where AI models fall short

Worth knowing before you plan a project around them.

AI meshes don't have the clean UV layouts or trim sheets of hand-made assets; use them for props, not modular kits.
Models are static; rig characters before using them with animation.

Questions

Something else? Ask us and a person will answer.

Can Unreal Engine import GLB?

Yes. Unreal Engine 5 imports .gltf and .glb through its Interchange pipeline: use Import in the Content Browser, drag and drop, or File, Import Into Level.

Do I need FBX?

Not for static props. GLB carries the mesh and PBR materials in one file.

Will the materials look right?

The colour, normal and metal-roughness maps import as a PBR material. Tweak roughness to taste under your lighting.

Why does my model come out the wrong size?

GLB is measured in metres and AI models are usually about a metre across. Scale it in your tool, or use the free converter, which can set an exact height in millimetres for printing.
