Do the pieces tile perfectly?

They're designed with flat bases and straight sides, but AI meshes aren't CAD-exact; scale and snap them to your grid in-engine.

Exports place the pivot at the bottom centre, so pieces drop straight onto the floor grid in Unity, Unreal, Godot and Roblox.

Examples

Made with this template

The card in the corner shows what went in.

Modular wooden dock segment — A wooden dock walkway segment

Modular sci-fi wall panel — A sci-fi corridor wall panel with lights

Modular ruined archway — A ruined stone archway

Each example is an actual run of this template at Standard quality, made from a typed idea or a sketch.

How it works

From idea to file in about 2–3 min

Type what you want, then wait while 2 AI steps run. Nothing to set up.

AI draws your idea
Image Studio turns your text or sketch into a clean concept render. The modular template asks for flat bottoms and straight connecting sides. The object is isolated on white so the 3D step sees one clear shape.

You download the file
As FBX or GLB. You can use it however you like.

After the download

Import it like any other asset

Drag the FBX or GLB into your project. Scale and texture size are already set for the engine you pick.

Drop it into Unity, Unreal / UEFN, Godot

Export presets set the format, scale and texture size for each engine.

Prototype in minutes

Fill a level with props before you commit to final art.

Keep one style

Every asset uses the same locked style, so a whole set looks like one game.

Edit it in Blender

GLB opens in Blender if you want to tweak, rig or re-texture it.

Behind the scenes

How this template works

Image Studio designs the asset in a fixed style, then Image to 3D builds it within a 4,000-face polygon budget. The export presets set format, scale and texture size for your engine.

Do it yourself for more control

Change the style text in the Image Studio prompt to match your game's art direction.
Use Remesh to hit an exact triangle count or get quad topology.
Use LOD to generate lighter versions for distant objects.
Snap pieces in-engine with the grid size matching the piece width.

What is 3D AI Studio?

3D AI Studio is a web app that makes 3D models, images and sounds with AI. It runs in your browser, so there is nothing to install.

A template is a saved recipe. It runs a fixed set of AI tools with settings we've already tested, so all you add is a photo or a sentence.

Runs in your browserPhone or computer

Inside this template

Step 1
Image Studio
Draws a picture from a sentence or a sketch.
Step 2
Image to 3D
Turns a single picture into a textured 3D model.

How to describe it

Describe one object, not a scene: "a wooden barrel with iron rings".
A rough sketch is enough; notes and arrows on the paper are ignored.
Make several assets with the same template to build a matching set.

Good to know: Pieces aren't dimensionally exact; scale them to your grid unit after import.

MCP connector

Run this template from Claude, ChatGPT or Cursor

Connect the 3D AI Studio MCP to your AI assistant and paste the brief into the chat. It runs the same steps with the same prompts and settings, shows you the result in the conversation and saves it to your library.

Condition

Overgrowth

Connect the MCP once in your account settings. It's included in every paid plan.

Chat brief · Stylized Modular Piece

Use the 3D AI Studio MCP to run the "Stylized Modular Piece" template (https://www.3daistudio.com/templates/modular-game-assets) for me.

My idea: A stone castle wall segment with a torch
Condition: Intact
Overgrowth: None

Follow these steps in order. The prompts and settings are the template's own, so use them word for word and only put my idea where it says {MY IDEA}.

1. Design the asset
Call generate_image_nano_2_1 with aspect_ratio "1:1", resolution "1K", output_format "png" and this prompt:
"""
A finished 3D game asset render of {MY IDEA}. Style: stylized hand-painted 3D game asset like a fantasy RPG prop, exaggerated chunky proportions, painterly hand-painted textures with soft gradients and warm highlights. A modular level-building piece with a flat bottom so it sits on a grid, straight vertical sides where it would connect to the next piece. One single isolated object only, centered, shown in a three-quarter front view from slightly above, the entire object visible with generous empty margin. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no ground plane, no text, no labels, no annotations, no arrows.
"""
If I want to start from a sketch or reference image instead, call upload_image so I can hand it over, then call edit_image_gpt with the upload in images, quality "low", output_format "png" and this prompt:
"""
This is a rough sketch. Recreate the object it shows as a finished 3D game asset render, keeping the sketch's design, proportions and key details, and ignore any handwritten notes, arrows and paper. Style: stylized hand-painted 3D game asset like a fantasy RPG prop, exaggerated chunky proportions, painterly hand-painted textures with soft gradients and warm highlights. A modular level-building piece with a flat bottom so it sits on a grid, straight vertical sides where it would connect to the next piece. One single isolated object only, centered, shown in a three-quarter front view from slightly above, the entire object visible with generous empty margin. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no ground plane, no text, no labels, no annotations, no arrows.
"""

2. Build the 3D model
Call generate_prism_3_1 with the task_id of the image from step 1 in images, texture_model "3.5", texture_quality "fast", geometry_quality "standard", pbr false, face_limit 4000.
For a lighter, game-optimized mesh with clean low-poly topology, call generate_p2 instead with texture_model "3.5", texture_quality "standard", pbr false and no face_limit.

3. Export
Export it for Unity unless I name another target: call convert_model on the 3D model with output_format "fbx_zip" (FBX with its textures) for Unity, Unreal / UEFN or Roblox Studio. Godot or Blender take the generated GLB as it is, no conversion needed.

After each generation call, keep polling get_generation with its task_id until it completes, then show me the result with show_generation before you start the next step.

Or automate it with the API

The same tools are available through the 3D AI Studio API. Call them from your own code to make hundreds at once, build them into your app or run them in your pipeline.
