Convert Your 3D Mesh/Model LWO Files to GLB

to

Our free and fast tool will convert most 3D mesh or LWO (LightWave Object File) model files to a standard GLB (Graphics Language Transmission Format) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple LWO files; up to 25 files at a time can be converted.

To convert your LWO file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a GLB file and will be ready for download shortly afterwards. For more information about the LWO to GLB conversion process, see the conversion information section below.

Frequently Asked Questions

How can I convert my LWO file to GLB?

First click the "Upload..." button, select your LWO file to upload. Select any configuration options. When the LWO to GLB conversion has completed, you can download your GLB file straight away.

How long does it take to convert my LWO to GLB?

We aim to process all LWO to GLB conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the LWO to GLB conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my LWO to GLB on ImageToStl.com?

Yes, of course! We do not store the LWO file you submit to us. The resulting GLB file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert my LWO to GLB on Windows, Linux, Android, iOS or Mac OS?

Yes! Our LWO to GLB tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our LWO conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

My LWO file contains textures, how do I upload these?

If your LWO file has separate texture (PNG, JPG etc.) files, you can place these additional files, along with the LWO file within a ZIP or other compressed archive file and upload this.

I have several LWO files; can I batch convert my LWO to GLB?

Yes! Our LWO tool supports full batch conversions. You can upload up to 25 and LWO files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the GLB files individually or download them all in a single ZIP file.

Description

The LWO, or LightWave 3D Object file, is a 3D graphics file format originally released in 1990 and available for the Amiga, Mac OS, and Windows. The LightWave software was developed by NewTek and is used in the television and film production of 3D digital effects.

The LightWave software is still a popular choice for 3D modeling and digital effects, with the most recent version being released in 2021. The format can contain 3D model or mesh information along with material and animations.

LWO Notes

If your LWO file is uploaded with accompanying texture files, these will be included in the conversion process.

Description

The GLB file format, which can also have the GLTF file extension depending on whether the content is binary or text/JSON, is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLB format is an open standard that is maintained by the Khronos Group.

GLB Notes

If your original model file contains texture images and other texture-related data, these will be included in the final GLB file.

Supported Features

  • V2.0 and above files only
  • Mesh geometry
  • Materials
  • Textures

Unsupported Features

  • Animations

How does it work?

Converting from the LWO file format to GLB can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your LWO file to a valid GLB 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source LWO File

In its simplest form, an LWO file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

When our tool reads this 3D data, all we are interested in are the vertices, faces, normals, materials, and textures, as this is the only data that can be accurately converted into the final GLB file.

The LWO file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an GLB file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the LWO file.

For more information regarding the LWO file format, please see this great article that goes into a lot of detail explaining the LWO format.

Step 2: Process File Data

With the LWO file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the GLB format.

Step 3: Saving to the GLB Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the GLB format.

Along with the completed GLB file, any textures that were present in the original LWO file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.
