- Image to 3D3AIAI builds it in 3D
Image to 3D (Prism 3.1) builds the mesh with a 15,000-face face limit and Fast textures, so it's light enough for real-time use.
- FBX GLB4YoursYou download the file
As FBX or GLB. You can use it however you like.
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.
Export presets set the format, scale and texture size for each engine.
Fill a level with props before you commit to final art.
Every asset uses the same locked style, so a whole set looks like one game.
GLB opens in Blender if you want to tweak, rig or re-texture it.
How this template works
Image Studio designs the asset in a fixed style, then Image to 3D builds it within a 15,000-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.
- Line several dioramas up edge to edge to build a level map or world-select screen.
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.
- Step 1Image Studio
Draws a picture from a sentence or a sketch.
- Step 2Image to 3D
Turns a single picture into a textured 3D model.
What you need
- One sentence or a sketchNo prompt skills needed

stylized hand-painted 3D game asset like a fantasy RPG prop, exaggerated chunky proportions, painterly hand-painted textures with soft gradients and warm highlights.
low-poly 3D game asset, faceted flat-shaded geometric planes, simplified chunky shapes, a limited palette of flat colours, no texture noise, like a stylized mobile game prop.
cozy stylized 3D game asset like a life-sim game, soft rounded shapes with gently bevelled edges, warm pastel colours and clean simple painted textures.
The files you get
Drag it into Unity, Unreal or Roblox Studio.
For Godot, Blender, websites and AR viewers.
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: The scene is one mesh; split props off with Segmentation if you need them separate.
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.
- Connect the MCP once in your account settings. It's included in every paid plan.
- Copy the brief and swap the example in the first line for your own.
- Paste it into a new chat. Your assistant runs every step and shows you each result.

My idea: A cozy cabin by a lake with a wooden dock
Style: Hand-painted
Season: Summer
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 diorama
Call generate_image_nano_2_1 with aspect_ratio "1:1", resolution "1K", output_format "png" and this prompt:
"""
A finished 3D game diorama 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. One single miniature diorama: a small square chunk of land with thick earth and stone sides cut straight down, the whole scene built on top of it and attached to it, tiny and cosy with a few clear focal points and no floating parts. Shown in an isometric view from above at a three-quarter angle, the entire diorama visible with generous empty margin. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no text.
"""
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. One single miniature diorama: a small square chunk of land with thick earth and stone sides cut straight down, the whole scene built on top of it and attached to it, tiny and cosy with a few clear focal points and no floating parts. Shown in an isometric view from above at a three-quarter angle, the entire diorama visible with generous empty margin. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no text.
"""
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 15000.
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.
For Roblox, the mesh has to stay under 8,000 faces: pass face_limit 8000 to the 3D step.
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.
