ComfyUI Node: CGA_BlenderBridge

CGA_BlenderBridge :

The CGA_BlenderBridge node is designed to facilitate the seamless transfer of 3D models from ComfyUI to Blender, enabling real-time collaboration between these two powerful tools. This node acts as a bridge, allowing you to send 3D model files directly to Blender, where they can be further manipulated and rendered. By leveraging this node, you can streamline your workflow, reduce the time spent on manual file transfers, and ensure that your 3D models are accurately imported into Blender for further processing. The primary goal of the CGA_BlenderBridge node is to enhance productivity and efficiency for AI artists by providing a reliable and straightforward method for integrating ComfyUI-generated models into Blender's robust 3D environment.

CGA_BlenderBridge Input Parameters:

model_path

The model_path parameter is a string that specifies the absolute path to the 3D model file you wish to send to Blender. This parameter is crucial as it determines which model will be transferred. The path must be accurate and point to a valid file on your system. The node supports several common 3D file formats, including .obj, .fbx, .glb, and .gltf. If the path is incorrect or the file format is unsupported, the node will not function as intended. The default value is an empty string, and it does not support multiline or dynamic prompts.

port

The port parameter is an integer that specifies the port number on which Blender is listening for incoming connections. This must match the port number configured in Blender to establish a successful connection. The port number must be within the range of 1024 to 65535, with a default value of 54321. This parameter is essential for network communication between ComfyUI and Blender, and any mismatch or incorrect configuration can lead to connection issues.

CGA_BlenderBridge Output Parameters:

None

The CGA_BlenderBridge node does not produce any direct output parameters. Its primary function is to facilitate the transfer of 3D models to Blender, and as such, it does not return any values or data upon execution.

CGA_BlenderBridge Usage Tips:

• Ensure that the model_path is correctly specified and points to a valid 3D model file in a supported format to avoid errors during the transfer process.
• Verify that the port number matches the one configured in Blender to establish a successful connection. This is crucial for the node to function correctly.
• Before using the node, make sure that the Blender server is running and ready to accept incoming connections to prevent connection errors.

CGA_BlenderBridge Common Errors and Solutions:

File does not exist: <file_path>

• Explanation: This error occurs when the specified file path does not point to an existing file.
• Solution: Double-check the model_path to ensure it is correct and that the file exists at the specified location.

Unsupported format: <file_extension>

• Explanation: The file format of the specified model is not supported by the node.
• Solution: Convert the model to a supported format such as .obj, .fbx, .glb, or .gltf and update the model_path accordingly.

Connection refused (port <port_number>). Ensure Blender server is running!

• Explanation: The node is unable to connect to Blender because the server is not running or the port number is incorrect.
• Solution: Start the Blender server and verify that the port number matches the one specified in the node's port parameter.

Network error: <error_details>

• Explanation: A general network error occurred during the connection attempt.
• Solution: Check your network settings and ensure there are no firewall or security settings blocking the connection. Retry the operation after resolving any network issues.
