set_texture
Apply downloaded Polyhaven textures to 3D objects in Blender using texture IDs and object names for visual customization.
Instructions
Apply a previously downloaded Polyhaven texture to an object.
Parameters:
- object_name: Name of the object to apply the texture to
- texture_id: ID of the Polyhaven texture to apply (must be downloaded first)
Returns a message indicating success or failure.Input Schema

Implementation Reference
- src/server.py:620-672 (handler)The main handler function for the 'set_texture' MCP tool. It is decorated with @mcp.tool() for automatic registration. The function connects to Blender, sends the 'set_texture' command with object_name and texture_id parameters, processes the result, and returns a detailed success message including material information and node details, or an error message.
