ComfyUI-Lux3D Nodes

English / 中文

🌐 Official Website: Lux3D China | Lux3D Global

A ComfyUI extension that turns text descriptions or 2D images into 3D models in your workflow.

Model postprocessing

Five Lux3D/Postprocess nodes support Mesh Segmentation, Retopology, Articulation, Humanoid Rigging and Humanoid Animation. Retopology accepts a public or local GLB, a required face budget, topology mode and optional texture baking; its fixed outputs are GLB, OBJ and an optional OBJ ZIP.

Humanoid Animation supports separate/combined, GLB/FBX and in-place motion, with visible partial failures and complete actions_json. GLB Viewer provides clip selection. Articulation preserves the actual result format; download ZIP results instead of connecting them to the GLB Viewer.

Recommended Basic Workflows

The current release provides twelve nodes, which can be combined as needed.

Lux3D Image to 3D

1. Find Lux3D Image to 3D under Lux3D/Generate.

2. Provide at least one source in image_1 through image_8. Each slot accepts a public HTTP(S) URL, an upstream STRING URL, or one IMAGE, and the source types may be mixed.

3. (Optional) When you have one reference image and want to complete the remaining views, add Lux3D Multi-View Generator between Load Image and Lux3D Image to 3D, then connect image_1 through image_4 to the matching Image to 3D inputs. When you already have multiple views, connect them directly to image_1 through image_8 without using Multi-View Generator.

4. Select base_api_path, the generation version, face count, and required output formats. Include glb when you need an in-canvas preview; Multi-Format Export accepts either the generated glb or lux3d_zip.

5. Run the workflow.

6. After polling completes, the node returns task_id, lux3d_zip, glb, and ply. A format that was not requested or returned is an empty string.

7. (Optional) Connect a non-empty glb or ply output to Lux3D Viewer for in-canvas preview. When you need USDZ, OBJ ZIP, FBX ZIP, or other formats, connect either glb or lux3d_zip to Lux3D Multi-Format Export.

Lux3D Text to 3D

1. Find Lux3D Text to 3D under Lux3D/Generate.

2. Enter a text prompt describing the object.

3. Optionally enter a public HTTP(S) URL in reference_image, connect an upstream STRING URL, or connect one reference IMAGE.

4. Choose a style from the dropdown:

   • photorealistic: Photorealistic (default)
   • cartoon: Cartoon
   • anime: Anime
   • hand_painted: Hand-painted
   • cyberpunk: Cyberpunk
   • fantasy: Fantasy
   • glass: Glass

5. Select base_api_path, the generation version, face count, and required output formats. Include glb when you need an in-canvas preview; Multi-Format Export accepts either the generated glb or lux3d_zip.

6. Run the workflow.

7. After polling completes, the node returns task_id, lux3d_zip, glb, and ply.

8. (Optional) Connect a non-empty glb or ply output to Lux3D Viewer for in-canvas preview. When you need USDZ, OBJ ZIP, FBX ZIP, or other formats, connect either glb or lux3d_zip to Lux3D Multi-Format Export.

Lux3D Single Image Generator

1. Add Lux3D Single Image Generator from Lux3D/Generate.

2. Optionally enter a public HTTP(S) URL in image, connect an upstream STRING URL, or connect one IMAGE. Optionally enter a multiline prompt. At least one of image and prompt is required.

3. Select base_api_path and run the workflow. The node creates and polls the task internally, then returns task_id and image_url. Image-only input still produces a newly generated image; the source URL is not passed through as the result.

Lux3D Multi-View Generator

1. Add Lux3D Multi-View Generator from Lux3D/Generate.

2. Optionally enter a public HTTP(S) URL in image, connect an upstream STRING URL, or connect one IMAGE. Optionally enter a multiline prompt. At least one of image and prompt is required, so the node supports image-only, text-only, and image-plus-text generation.

3. Select base_api_path and run the workflow. The node returns task_id and four image URLs in a stable order: image_1 = FRONT_THREE_QUARTER, image_2 = OPPOSITE_THREE_QUARTER, image_3 = SIDE, and image_4 = BACK.

Lux3D Multi-Format Export

1. Add Lux3D Multi-Format Export from Lux3D/Export.

2. Enter a public .glb / .zip URL in model_url, connect an upstream STRING URL, or use the node's button to select a ComfyUI-local model.

3. Select the export formats. A GLB input requires at least one explicit format; a ZIP input may use default.

4. Run the workflow. The node returns task_id, glb, usdz, obj_zip, fbx_zip, stl, 3mf, and lux3d_zip, in that order. The first five sockets retain their historical positions; unrequested or unavailable results are empty strings.

5. For a ZIP input, lux3d_zip returns the source Lux3D ZIP and glb returns the default GLB export. For a GLB input, glb returns the original model URL and lux3d_zip is empty.

Lux3D Material Redraw

1. Find the Lux3D Material Redraw node under the Lux3D category in the ComfyUI node library.

2. Enter a public HTTP(S) URL in image, connect an upstream STRING URL, or connect one material-reference IMAGE.

3. Enter a public GLB URL in mesh_url, connect an upstream STRING URL, or use the node's button to select a ComfyUI-local GLB.

4. Run the workflow. The node returns a new glb_model_url with the redrawn material.

5. The returned model URL can be connected to the Lux3D Viewer node for in-canvas preview.

Lux3D Mesh Segmentation

1. Add Lux3D Mesh Segmentation from Lux3D/Postprocess.

2. Enter a public GLB URL in model_url, connect the glb output of an Image to 3D or Text to 3D node, or use the node's button to select a ComfyUI-local GLB.

3. Select base_api_path and run the workflow. Local models are uploaded first. After polling completes, the node returns task_id and a glb containing the reconstructed parts.

4. Connect glb to Lux3D Viewer for preview or download it from the result panel. If the account already has a part-splitting task in progress, wait for it to finish before submitting another.

Lux3D Retopology

1. Add Lux3D Retopology from Lux3D/Postprocess.

2. Enter a public GLB URL in model_url, connect an upstream glb output, or select a ComfyUI-local GLB. Input must be static and non-Draco, without bones, skinning, animation, or morph targets.

3. Enter the required face_limit, such as 5000, and use quad to choose quad or triangle topology. Enable bake_textures and select texture_size when texture baking is needed.

4. Select base_api_path and run the workflow. The node returns task_id, glb, OBJ Untextured, and OBJ Textured (a textured OBJ ZIP). The last output is empty when no texture package is generated; the result panel reports a missing package if baking was requested.

5. Connect glb to Lux3D Viewer for preview. Download the untextured OBJ and any returned texture ZIP from the result panel. Use OBJ to inspect quad topology; GLB is always triangulated.

6. If polling times out or is interrupted, enter the recorded task ID in resume_task_id, keep the original account, base_api_path, and bake_textures setting, and run again. This only queries the original task; it does not upload the model, create a task, or change the original parameters.

Lux3D Articulation

1. Add Lux3D Articulation from Lux3D/Postprocess.

2. Enter a public GLB URL in model_url, connect the glb output of a generation or Mesh Segmentation node, or select a ComfyUI-local GLB.

3. Use prompt to describe the moving parts, fixed parts, and desired motion, for example: "Keep the base fixed and slowly open and close the lid around its hinge."

4. Select base_api_path and run the workflow. The node returns task_id and the final file's result_url.

5. For a GLB result, connect result_url to Lux3D Viewer to preview the motion. Download ZIP or other formats from the result panel.

Lux3D Humanoid Rigging

1. Add Lux3D Humanoid Rigging from Lux3D/Postprocess.

2. Enter the character model's public HTTPS GLB URL in model_url, connect an upstream glb output, or select a ComfyUI-local GLB. Local models are uploaded first.

3. Select base_api_path and run the workflow. After polling completes, the node returns task_id and the rigged glb.

4. Connect glb to Lux3D Viewer for preview, or to model_url on Lux3D Humanoid Animation to generate character motions.

Lux3D Humanoid Animation

1. Add Lux3D Humanoid Animation from Lux3D/Postprocess.

2. Connect the glb output of Lux3D Humanoid Rigging to model_url. For an existing rigged model, enter a public HTTPS GLB URL or select a ComfyUI-local GLB.

3. Select an action in Action to add and click Add action, or enter a JSON array or one action ID per line in animation_ids, such as ["Walk_Loop", "Idle_Loop"]. Choose 1–10 distinct, case-sensitive IDs.

4. Set output_mode to separate for one file per action or combined for one file with independent animation clips. Set out_format to glb or fbx, and enable animate_in_place for in-place motion.

5. Select base_api_path and run the workflow. The node returns task_id, the first successful glb or fbx, and actions_json containing every action's status, result URL, or failure reason. Download other successful results from the result panel.

6. For GLB output, connect glb to Lux3D Viewer to play the animation; combined output supports clip selection. Download the original FBX file from the result panel and open it in your target 3D application.

Lux3D Viewer

1. Add Lux3D Viewer from the Lux3D category.

2. Connect an upstream glb / ply URL to model_url, enter a public URL manually, or use the node's button to select a ComfyUI-local .glb / .ply file.

3. Run the workflow to preview the model in the canvas and return the resolved model_url. Local models are never uploaded to Lux3D.

4. GLB animations play automatically when present. Use the animation clip dropdown in the preview to switch motions.

Node Reference

The current release registers twelve nodes. Generation, export, material-redraw, and postprocessing nodes create asynchronous tasks internally and poll until completion, with up to 60 checks at 15-second intervals (about 15 minutes). Retopology only queries an existing task when resume_task_id is set.

Common conventions:

• base_api_path accepts https://api.aholo3d.cn (China) or https://api.aholo.ai (international). Do not add a trailing slash.
• Nodes other than Lux3D Viewer no longer expose an API-key input. Set LUX3D_API_KEY_CN or LUX3D_API_KEY_INTL in the ComfyUI server environment to match base_api_path.
• Image fields typed as STRING / IMAGE accept a public HTTP(S) URL, an upstream STRING URL, or a connected ComfyUI IMAGE containing exactly one image. Local images are uploaded through Asset/OUS before the Lux3D task is submitted; nodes use the resulting asset URL and do not expose Base64 data URLs.
• Model fields with local-file support provide a picker for the ComfyUI input directory and also accept relative files from output or temp (marked with [output] or [temp]). Local models used by Lux3D tasks are uploaded first.
• The multi-format service returns seven fixed slots in zipUrl, glbUrl, usdzUrl, objZipUrl, fbxZipUrl, stlUrl, threeMfUrl order. The plugin maps these slots by position rather than inferring formats from filenames; a format that was not requested or returned is represented by an empty string.
• All five postprocessing nodes use the Lux3D/Postprocess category. Their result panels show the task ID, available download links, and warnings or per-action status. GLB can connect to Viewer; use download links for OBJ, ZIP, and FBX.

Lux3D Viewer

Category: Lux3D

Previews a GLB model or PLY Gaussian-splat file in the ComfyUI canvas. Remote URLs pass through unchanged. Local files are not uploaded; they are converted to a same-origin ComfyUI /view URL.

GLB preview uses the same model-viewer 4.2.0 runtime and preset as the Web GLB Viewer: black background, the same HDR environment, exposure 0.95, auto tone mapping, a 30° field of view, and a 125% initial camera distance. Shadows and auto-rotation are disabled; orbit, zoom, pan, and model animation remain enabled. Runtime, HDR, and decoders are bundled locally. Restart ComfyUI and refresh the browser after updating the plugin's viewer assets.

Lux3D Retopology

Category: Lux3D/Postprocess

Rebuilds the topology of a static, non-Draco GLB. Bones, skinning, animation, and morph targets are unsupported, and original part boundaries may not be preserved. The target face count is a budget rather than a guarantee of an exact count or all-quad topology. OBJ is the topology geometry result; GLB is always triangulated.

Inputs

Input	Type	Description
base_api_path	STRING	Lux3D API endpoint: https://api.aholo3d.cn (China) or https://api.aholo.ai (international)
model_url	STRING / model source	Public HTTP(S) static .glb URL, upstream STRING output, or a local ComfyUI .glb file
face_limit	INT	Required face budget: 1000–500000 for quads or 2000–1000000 for triangles. The default 0 means not set and cannot be used to create a task
quad	BOOLEAN	Uses quad topology when true (default), or triangle topology when false
bake_textures	BOOLEAN	Enables texture baking; defaults to false. Keep the original request's setting when resuming so a missing texture package is reported correctly
texture_size	Enum	512, 1024, 2048, or 4096; defaults to 2048. A valid value is required even when baking is disabled
content_id	STRING	Optional business correlation value; defaults to an empty string and is not an idempotency key
resume_task_id	STRING	Optional existing task ID; queries using the original account and region without uploading a model, creating a task, or changing the original parameters

Outputs

Output	Type	Description
task_id	STRING	Lux3D task ID
glb	STRING	Retopologized GLB URL for Viewer; includes textures when baking succeeds
OBJ Untextured	STRING	Standalone OBJ geometry URL preserving the topology generated by the service
OBJ Textured	STRING	ZIP URL containing OBJ, MTL, and textures; empty when no texture package is generated

Output positions remain fixed when the texture package is missing. The result panel shows only non-empty download links. If baking was requested but no ZIP was generated, it reports that geometry results are available but the texture package is missing; GLB and OBJ remain usable. Resume a timed-out or interrupted query with its recorded task ID. If task creation has an unknown outcome, check task history before submitting again.

Lux3D Articulation

Category: Lux3D/Postprocess

Adds joint motion to model parts from a GLB and a motion prompt. The final file format follows the actual service result. For a GLB result, connect result_url to Viewer; download ZIP or other formats from the result panel.

Automatically rigs a character GLB. Public model URLs must use HTTPS; local GLBs are uploaded first. The resulting rigged GLB can connect to Humanoid Animation.

Inputs

Input	Type	Description
base_api_path	STRING	Lux3D API endpoint: https://api.aholo3d.cn (China) or https://api.aholo.ai (international)
model_url	STRING / model source	Public HTTPS character .glb URL, upstream STRING output, or a local ComfyUI character .glb file

Outputs

Output	Type	Description
task_id	STRING	Lux3D task ID
glb	STRING	Rigged GLB URL; connects to Viewer or model_url on Lux3D Humanoid Animation

Lux3D Humanoid Animation

Category: Lux3D/Postprocess

Applies selected motions to a rigged GLB. Public model URLs must use HTTPS; local GLBs are uploaded first. The catalogue contains 85 public IDs, with 1–10 distinct actions per task, separate or combined output, and in-place motion support.

Inputs

Input	Type	Description
base_api_path	STRING	Lux3D API endpoint: https://api.aholo3d.cn (China) or https://api.aholo.ai (international)
model_url	STRING / model source	Public HTTPS rigged .glb URL, a rigging node's glb output, or a local ComfyUI rigged .glb file
animation_ids	STRING	1–10 distinct, case-sensitive public action IDs as a JSON array or one ID per line. Defaults to ["Walk_Loop"]; actions can also be added with the selection button
output_mode	Enum	separate (default) returns one file per action; combined returns one file with independent animation clips
out_format	Enum	glb (default) or fbx; FBX is the original file, not a ZIP
animate_in_place	BOOLEAN	Enables in-place motion; defaults to false

Outputs

Output	Type	Description
task_id	STRING	Lux3D task ID
glb	STRING	First successful result URL in GLB mode; empty in FBX mode
fbx	STRING	First successful result URL in FBX mode; empty in GLB mode
actions_json	STRING	JSON string containing an actions array in request order, with each action's ID, status, success URL, or failure reason

The result panel provides download links for every successful file and per-action status. Successful results remain usable when some actions fail; the node raises an error if all actions fail. GLB animations play in Viewer, with clip selection for combined output. Download FBX files and open them in your target 3D application.

FAQ

1. If the ComfyUI Manager shows a security-level warning when installing this plugin, adjust the corresponding security level in the ComfyUI Manager config and retry.

Configuration

Server environment variables

The currently registered nodes do not read config.txt or expose an API-key input in the workflow. Set the variable matching base_api_path in the environment of the process that starts ComfyUI:

base_api_path	Environment variable
https://api.aholo3d.cn	LUX3D_API_KEY_CN
https://api.aholo.ai	LUX3D_API_KEY_INTL

Existing workflows that explicitly store https://api.aholo3d.com continue to use that origin for upload credentials, generation, and task queries, with LUX3D_API_KEY_INTL. Updating the extension does not rewrite saved workflow addresses. To migrate, change each affected node's base_api_path to https://api.aholo.ai and save the workflow. The client adds /global; do not enter it in the field. Legacy API availability and its compatibility period depend on the gateway operator; accepting the old address does not guarantee it will remain available.

PowerShell example:

$env:LUX3D_API_KEY_CN = "your_cn_api_key"
$env:LUX3D_API_KEY_INTL = "your_intl_api_key"

Bash example:

export LUX3D_API_KEY_CN="your_cn_api_key"
export LUX3D_API_KEY_INTL="your_intl_api_key"

If you use only one region, set only its variable. The variables must be visible to the ComfyUI server process; restart ComfyUI after changing them. Lux3D Viewer does not call the Lux3D API and therefore needs no API key.
