name	generate-asset
description	Generate a 3D asset for Roblox using Blender MCP. Creates models from text descriptions via AI (Hyper3D/Hunyuan3D) or downloads from PolyHaven/Sketchfab, optimizes for Roblox constraints, and exports FBX.

/generate-asset — 3D Asset Generation

Delegate to: blender-mcp-operator

Steps

1. Gather Requirements

Ask:

• "What asset do you need?" (weapon, prop, character, environment piece, vehicle)
• "What style?" (low-poly, stylized, realistic, cartoon, sci-fi, fantasy)
• "Triangle budget?" (default: <5000 for props, <10000 for hero assets)
• "Any reference?" (image, description, similar game)

2. Choose Source

• AI generation (no reference exists): mcp__blender-mcp__generate_hyper3d_model_via_text
• From reference image: use /asset-from-image instead
• From library (generic asset): mcp__blender-mcp__search_polyhaven_assets or search_sketchfab_models

3. Generate / Download

• For AI: submit prompt, poll get_hyper3d_status until complete, import_generated_asset
• For library: download and import into Blender scene

4. Inspect

• mcp__blender-mcp__get_viewport_screenshot — visual review
• mcp__blender-mcp__get_object_info — check triangle count, dimensions, materials

5. Optimize for Roblox

Via mcp__blender-mcp__execute_blender_code:

• Decimate to target triangle budget
• Scale to Roblox units
• Set origin to base center
• UV unwrap if needed
• Apply clean topology (remove doubles, fix normals)

6. Export

• Export as FBX to assets/models/<asset-name>.fbx
• Verify file size

7. Preview and Approve

• mcp__blender-mcp__get_viewport_screenshot — final screenshot
• Present to user with: poly count, texture resolution, dimensions, screenshot
• Wait for approval before finalizing
