ComfyUI Node: SAM 3D Body: Preview Rigged Mesh

SAM 3D Body: Preview Rigged Mesh:

The SAM3DBodyPreviewRiggedMesh node is designed to facilitate the visualization of rigged 3D meshes in an interactive environment. Its primary function is to display FBX files, which are commonly used for 3D models, in a viewer that supports skeleton visualization and interactive bone manipulation. This node is particularly beneficial for artists and designers who need to preview and interact with 3D models that have been rigged, meaning they have a skeleton and skinning applied. By using this node, you can easily assess the structure and movement capabilities of your 3D models, ensuring that they meet your creative and technical requirements before finalizing them for production or further development.

SAM 3D Body: Preview Rigged Mesh Input Parameters:

fbx_output_path

The fbx_output_path parameter is a string that specifies the filename of the FBX file located in the output directory. This parameter is crucial as it directs the node to the correct file that needs to be previewed. The FBX file should already be exported and placed in the designated output directory by the SAM3D export node. This parameter does not have minimum or maximum values, but it must be a valid filename that exists in the output directory. The correct specification of this parameter ensures that the node can locate and display the intended 3D model for interactive preview.

SAM 3D Body: Preview Rigged Mesh Output Parameters:

This node does not produce any direct output parameters. Instead, it facilitates the visualization of the specified FBX file in an interactive viewer, allowing you to engage with the 3D model's skeleton and skinning features.

SAM 3D Body: Preview Rigged Mesh Usage Tips:

• Ensure that the FBX file is correctly exported and placed in the output directory before attempting to preview it with this node.
• Use the interactive features of the viewer to test the rigging and skinning of your 3D model, checking for any issues in the skeleton structure or movement.

SAM 3D Body: Preview Rigged Mesh Common Errors and Solutions:

RuntimeError: FBX file not found in output directory: <fbx_output_path>

• Explanation: This error occurs when the specified FBX file cannot be found in the output directory. It indicates that the file path provided does not match any existing file in the directory.
• Solution: Verify that the FBX file has been correctly exported and is located in the output directory. Double-check the fbx_output_path parameter to ensure it matches the filename of the exported FBX file.
