Blender MCP’s most powerful capability is assembling complete 3D scenes from a single prompt. By combining library assets, AI generation, and code execution, Claude can build environments that would take hours to assemble manually. Describe the scene you want, and Claude handles sourcing, importing, positioning, and lighting.

​
The Asset Priority Strategy

Claude follows a built-in priority when choosing where to source assets for your scene:

1. Sketchfab

Used first for specific, existing real-world objects when you need accuracy and detail.

2. Poly Pizza

Used for stylised and low-poly assets. Roughly 10,600 free models with light geometry.

3. Poly Haven

Used for generic environment assets, HDRIs for lighting, and PBR textures for surfaces.

4. Hyper3D / Hunyuan3D

Used for custom, unique items that do not exist in any library. Generated on demand from text or images.
This priority is applied automatically, so you do not need to specify sources in your prompts unless you have a preference.

​
Complete Scene Workflow

When you ask Claude to build a scene, it follows this structured process:
1

Inspect the current scene

Claude calls get_scene_info to see what objects already exist, their names, and their properties.
2

Take a viewport screenshot

Claude uses get_viewport_screenshot to see the visual state of the scene before making changes.
3

Check available integrations

Claude verifies which integrations are enabled (Poly Haven, Sketchfab, Poly Pizza, Hyper3D, Hunyuan3D) and has API keys configured.
4

Download assets from the best source

Based on the asset priority strategy, Claude selects the optimal source for each element and imports it.
5

Check bounding boxes and spatial relationships

Claude inspects imported objects to ensure correct scale, position, and non-overlapping placement.
6

Take a final screenshot

Claude captures the viewport again to verify the completed scene matches your request.

Generating Scenes from Reference Images

You can give Claude a reference image and ask it to recreate the scene in Blender. This is useful for matching concept art, photographs, or mood boards.

Three.js and Web Export

Blender MCP can bridge into web workflows. There is a demo showing how to get Blender scene info and generate a Three.js sketch from it, enabling rapid web-based 3D prototyping.

Tips for Large Scenes

For large scenes, build incrementally. Start with environment (HDRI + ground), then major elements, then props and details. This keeps each step manageable and lets you verify progress with get_viewport_screenshot.
If an asset imports at the wrong scale, ask Claude to check the bounding box with get_object_info and resize it before placing more objects.
