Behind the scenes

How this template works

Image Studio designs the asset in a fixed style, then Image to 3D builds it within a 8,000-face polygon budget. The export presets set format, scale and texture size for your engine.

  1. 1
    Step 1 · Image Studio

    Design the asset

    Image Studio turns your text or sketch into a clean concept render. The building template stands one building on a flat ground tile, seen from slightly above, so roof and entrance both read clearly. The object is isolated on white so the 3D step sees one clear shape.

    Open Image Studio
  2. 2
    Step 2 · Image to 3D

    Build the 3D model

    Image to 3D (Prism 3.1) builds the mesh with a 8,000-face face limit and Fast textures, so it's light enough for real-time use.

Tips for the best result

  • 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.

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 buildings up on the same grid size so streets snap together.

Good to know

Buildings are solid exteriors; interiors aren't modelled.

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.

Chat brief · Stylized Building
Use the 3D AI Studio MCP to run the "Stylized Building" template (https://www.3daistudio.com/templates/building-generator) for me.

My idea: A cosy medieval tavern with a thatched roof
Season: Summer
Condition: Well-kept

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. One single standalone building only, standing on a small flat square ground tile, shown in a three-quarter view from slightly above with the front door and roof clearly visible, the entire building visible with generous empty margin, no surrounding streets or other buildings. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no text, no signs with writing. Surface and light: soft, even, diffuse studio light. Metal, gems, glass-like and wet or glossy materials show what they are through colour and a soft satin sheen, never through mirror reflections, bright specular hot spots or reflections of the surroundings. Glowing parts (eyes, runes, lava, neon, gems) are painted as bright, flat emissive colour on the surface itself, with no light spilling onto nearby surfaces, no halo, bloom or glow around the object, and no light rays, sparkles or particles in the air.
"""
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 standalone building only, standing on a small flat square ground tile, shown in a three-quarter view from slightly above with the front door and roof clearly visible, the entire building visible with generous empty margin, no surrounding streets or other buildings. Seamless pure white (#FFFFFF) background, soft even studio lighting, no cast shadows, no text, no signs with writing. Surface and light: soft, even, diffuse studio light.

Glowing parts (eyes, runes, lava, neon, gems) are painted as bright, flat emissive colour on the surface itself, with no light spilling onto nearby surfaces, no halo, bloom or glow around the object, and no light rays, sparkles or particles in the air.
"""

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 8000, lighting_removal false.
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, lighting_removal 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.
