name: lux3d description: "Use Lux3D to generate 3D models from images or text, or perform material repaint. Trigger when the user asks for image to 3D, text to 3D, prompt to 3D, create a 3D model from a description, create a 3D model from a description plus a reference image, or regenerate materials for an existing 3D model. Supports v1.0-pro, v2.0-preview, v3.0-standard, and G1. G1 is the fast beta model with multi-view image input and zip/glb/ply output. For Global users."
What This Skill Does
Lux3D generates 3D assets through three documented asynchronous workflows:
- Image to 3D: submit an input image, poll the task, then download the ZIP result.
- Text to 3D: submit a prompt plus style, optionally with a reference image, poll the task, then download the ZIP result.
- Material Repaint: submit a reference image and a model URL, poll the task, then download the regenerated model result.
All workflows require LUX3D_API_KEY, which is the API key obtained from https://labs.aholo3d.com/api-keys.
API Endpoint
- Global Endpoint:
https://api.aholo3d.com/global
Concurrency Limits
Lux3D limits the number of generation tasks that can be in progress at the same time based on the account plan. Image-to-3D, text-to-3D, and material repaint tasks share the same account-level concurrency quota.
| Account Type | Maximum Concurrent In-progress Tasks |
|---|---|
| Free account | 1 |
| Pro account | 2 |
If a task creation endpoint returns GENERATION_CONCURRENCY_LIMIT_EXCEEDED, the account has reached its concurrency limit. No new task is created and no credits are consumed. Wait for an existing task to finish before retrying, or upgrade the account for higher concurrency.

Python Usage
G1 Image-to-3D
G1 accepts one local image through image_path and additional views through
imagePaths, for a total of 1-32 images. The client encodes local images as
complete Base64 Data URLs. Multiple views are sent in imgs; one view uses img.
from skill.lux3d_client import generate_3d_model
result = generate_3d_model(
"path/to/view-1.png",
imagePaths=["path/to/view-2.png"],
version="G1",
outputFormat=["zip"],
faceCount=200000,
enablePbr=True,
textureSize=1000,
)
G1 supports outputFormat=["zip"], ["glb"], and ["ply"]. glb returns
tex_mesh.glb when PBR is enabled and mesh.glb when enablePbr=False;
ply returns gaussian.ply; zip or an empty or omitted list returns
results.zip; a combined request returns and downloads multiple artifacts in
format order. faceCount affects Mesh only and does not affect
PLY 3DGS. G1 defaults are faceCount=200000, enablePbr=True, and
textureSize=1000.
Image to 3D
from skill.lux3d_client import generate_3d_model
result = generate_3d_model("path/to/input.jpg", version="v2.0-preview")
print(result)
Specify the target face count (optional; affects Mesh outputs only and does not affect 3DGS outputs; supported by v2.0-preview, v3.0-standard, and G1 in the range [10000, 500000]; when omitted, v2.0-preview and v3.0-standard use 60000, while G1 uses 200000; v1.0-pro ignores this parameter):
result = generate_3d_model("path/to/input.jpg", version="v3.0-standard", faceCount=100000)
print(result)
Or explicitly select the Global endpoint with the international region value:
result = generate_3d_model("path/to/input.jpg", region="international", version="v2.0-preview")
print(result)
Text to 3D
from skill.lux3d_client import generate_text_to_3d
result = generate_text_to_3d(
"Generate a high-quality 3D wooden chair",
style="photorealistic",
version="v2.0-preview",
)
print(result)
Specify target face count (affects Mesh only, not 3DGS; effective for v2.0-preview / v3.0-standard / G1):
result = generate_text_to_3d(
"Generate a high-quality 3D wooden chair",
style="photorealistic",
version="v3.0-standard",
faceCount=100000,
)
print(result)
Text plus Reference Image
G1 text-to-3D uses the same outputFormat, faceCount, enablePbr, and
textureSize options:
result = generate_text_to_3d(
"Generate a modern wooden dining chair",
version="G1",
outputFormat=["glb"],
enablePbr=False,
)
from skill.lux3d_client import generate_text_to_3d
result = generate_text_to_3d(
"Generate a premium ceramic vase with a glossy glaze",
style="glass",
image_path="path/to/reference.png",
version="v2.0-preview",
)
print(result)
Low-level Task APIs
from skill.lux3d_client import (
create_task,
create_text_to_3d_task,
create_material_transfer_task,
query_task_status,
download_model,
)
image_task_id = create_task("path/to/input.jpg")
text_task_id = create_text_to_3d_task(
"Generate a stylized toy robot",
style="cartoon",
image_path="path/to/reference.png",
)
material_task_id = create_material_transfer_task(
"path/to/reference.png",
meshUrl="https://qhstaticssl.kujiale.com/application/octetstream/1784776896628/material_transfer_model.glb",
)
image_model_url = query_task_status(image_task_id)
text_model_url = query_task_status(text_task_id)
material_model_url = query_task_status(material_task_id)
download_model(image_model_url, "image_to_3d.zip")
download_model(text_model_url, "text_to_3d.zip")
download_model(material_model_url, "material_transfer.zip")
Material Repaint
from skill.lux3d_client import generate_material_transfer
result = generate_material_transfer(
"path/to/reference.png",
meshUrl="https://qhstaticssl.kujiale.com/application/octetstream/1784776896628/material_transfer_model.glb",
version="v2.0-preview",
)
print(result)
Command Line Usage
Region Selection
Use --region or -r to select the Global endpoint with the international region value (default):
python lux3d_client.py --region international image input.jpg output.zip
Or omit the region flag; Global is the default endpoint (international region value):
python lux3d_client.py image input.jpg output.zip
Image to 3D
# Historical form (default region)
python lux3d_client.py input.jpg output.zip --version v3.0-standard
# Explicit command
python lux3d_client.py image input.jpg output.zip --version v3.0-standard
Text to 3D
python lux3d_client.py text "Generate a high-quality 3D wooden chair" output.zip --style photorealistic --version v3.0-standard

Output Format
Pass outputFormat as a string for backward compatibility or as a list for the
unified API field outputFormat. v2.0-preview and v3.0-standard support zip, glb, usdz,
obj_zip, and fbx_zip. G1 supports
only zip, glb, and ply. When a result contains multiple URLs, downloading
without a selected format defaults to zip.
Lux3D Version
You can specify the Lux3D version via the version parameter:
| Version | Description | Output Format |
|---|---|---|
v3.0-standard |
Default version, adds colored transparent material support, reduces color deviation in generated models, improves material quality, preserves text and texture details, and adds custom face count support; supports five-format output | .zip + .glb + .usdz + _obj.zip + _fbx.zip |
v2.0-preview |
2.0 model architecture with enhanced text and texture detail preservation, no transparent material support | .zip + .glb + .usdz + _obj.zip + _fbx.zip |
v1.0-pro |
First-generation model with complete PBR material properties, supports transparent material generation | ZIP result |
G1 |
Fast beta model with single-view or multi-view input, optional PBR mesh, and 3DGS output; excels at generating plush-material 3DGS assets | results.zip, tex_mesh.glb/mesh.glb, or gaussian.ply |
Important: If the version parameter is not provided in the request, the system will default to v3.0-standard.
Custom face count: faceCount is optional and specifies the target face count for image-to-3D / text-to-3D Mesh generation. It affects Mesh outputs only and does not affect 3DGS outputs. v2.0-preview, v3.0-standard, and G1 support custom face counts in the range [10000, 500000]. When omitted, v2.0-preview and v3.0-standard use 60000, while G1 uses 200000; v1.0-pro ignores this parameter.
All generation APIs (image-to-3D, text-to-3D, material repaint) support the version parameter.
Specify Version in Python
# Image to 3D with version
result = generate_3d_model("path/to/input.jpg", version="v3.0-standard")
# Text to 3D with version
result = generate_text_to_3d(
"Generate a high-quality 3D wooden chair",
style="photorealistic",
version="v3.0-standard",
)
# Material repaint with version
result = generate_material_transfer(
"path/to/reference.png",
meshUrl="https://qhstaticssl.kujiale.com/application/octetstream/1784776896628/material_transfer_model.glb",
version="v3.0-standard",
)
Specify Version in Command Line
# Image to 3D with version
python lux3d_client.py image input.jpg output.zip --version v3.0-standard
# Text to 3D with version
python lux3d_client.py text "Generate a high-quality 3D wooden chair" output.zip --style photorealistic --version v3.0-standard
# Material repaint with version
python lux3d_client.py material reference.png output.zip --mesh-url https://qhstaticssl.kujiale.com/application/octetstream/1784776896628/material_transfer_model.glb --version v3.0-standard
Output
v3.0-standard Multi-format Output
The v3.0-standard version supports five model format outputs. You can choose the appropriate format based on your use case:
| Format | Description | Use Case |
|---|---|---|
| .zip | Packaged result containing GLB model and separate PBR texture assets | Material editing or custom rendering pipelines |
| .glb | GLB model with embedded materials | Web rendering, Unity/Unreal engine import, most 3D software |
| .usdz | Apple AR native format | iOS/macOS AR Quick Look, ARKit applications |
| _obj.zip | OBJ + MTL + BaseColor textures packed in a ZIP | Common 3D software and DCC tools |
| _fbx.zip | FBX model and .fbm texture directory packed in a ZIP | Maya, 3ds Max, Blender, and other mainstream DCC tools |
Download Different Formats
Choose formats at task creation time through list-form outputFormat. Do not append ?format= to a result URL:
result = generate_3d_model(
"path/to/input.jpg",
version="v3.0-standard",
outputFormat=["glb"],
)
v2.0-preview and v3.0-standard support zip, glb, usdz, obj_zip, and fbx_zip. Classic optional slots that were not requested may return NOT_REQUESTED; a multi-format request downloads ZIP by default.
v2.0-preview Multi-format Output
The v2.0-preview version supports five model format outputs:
| Format | Description | Use Case |
|---|---|---|
| .zip | Packaged result containing GLB model and separate PBR texture assets | Material editing or custom rendering pipelines |
| .glb | GLB model with embedded materials | Web rendering, Unity/Unreal engine import, most 3D software |
| .usdz | Apple AR native format | iOS/macOS AR Quick Look, ARKit applications |
| _obj.zip | OBJ + MTL + BaseColor textures packed in a ZIP | Common 3D software and DCC tools |
| _fbx.zip | FBX model and .fbm texture directory packed in a ZIP | Maya, 3ds Max, Blender, and other DCC tools |
v1.0-pro Output
The v1.0-pro version returns a single ZIP result containing:
- A GLB model file
- Complete PBR texture assets (with transparent material support)
Result Validity
All format download links are valid for 2 hours, please download promptly.
Notes
- Authentication uses
Authorizationheader:Authorization: <apiKey> - Image-to-3D, text-to-3D, and material repaint use different create endpoints
- All three workflows share the same task query endpoint
promptandstyleare required for text-to-3Dimgis optional for text-to-3D and should be a full data URL after encoding- Material repaint requires
img(reference image) andmeshUrl(model GLB file URL) parameters
Requirements
pip install Pillow requests
