Blender Asset Pipeline

Blender MCP Server

The Blender MCP server is a plugin running inside Blender. It drives modeling, material setup, AI generation, and marketplace imports.

Before any operation

• Check connection status with get_scene_info
• Use ToolSearch to discover available Blender MCP tools

Core tools

• execute_blender_code — run arbitrary Blender Python for modeling, materials, transforms
• get_scene_info / get_object_info — inspect current state
• get_viewport_screenshot — visual verification after any change
• set_texture — apply textures to objects
• import_generated_asset / import_generated_asset_hunyuan — bring AI-generated models in

AI Mesh Generation

Hyper3D Rodin

• generate_hyper3d_model_via_text or generate_hyper3d_model_via_images → get_hyper3d_status / poll_rodin_job_status → import_generated_asset
• Best for: concept art to 3D, text-described objects

Hunyuan3D

• generate_hunyuan3d_model → get_hunyuan3d_status / poll_hunyuan_job_status → import_generated_asset_hunyuan
• Best for: alternative generation when Rodin results aren't suitable

Always review AI-generated assets

• Screenshot after import with get_viewport_screenshot
• Check topology, scale, material assignments before export

Asset Marketplaces

PolyHaven

• get_polyhaven_status → get_polyhaven_categories → search_polyhaven_assets → download_polyhaven_asset
• High-quality CC0 models, HDRIs, and textures

Sketchfab

• get_sketchfab_status → search_sketchfab_models → get_sketchfab_model_preview → download_sketchfab_model
• Vast library, check licensing per model

Asset Pipeline: Blender → Godot

Export workflow

1. Apply all transforms (Ctrl+A → All Transforms)
2. Verify materials are PBR-compatible (Principled BSDF)
3. Check UV mapping — unwrap if needed
4. Export as glTF 2.0 (.glb or .gltf) to Godot project assets directory
5. Import to Godot, verify materials and textures render correctly
6. Test in scene at correct scale

Material considerations

• Use Principled BSDF node for Godot compatibility
• Bake procedural textures to images before export
• Pack textures into .glb for single-file distribution
• Check normal map format (OpenGL vs DirectX) matches Godot expectations

Scale and orientation

• Blender: Z-up, meters by default
• Godot: Y-up — glTF handles the conversion
• Verify scale after import; adjust export scale if needed
