What is an LWO file?

LWO files mostly belong to LightWave 3D by NewTek. LWO file extension is typically used to store 3D objects created using LightWave 3D, a cross-platform 3D modelling and animation software. Contents of LWO 3D object files include polygons, points, surfaces, references to textures, as well as data for rendering a 3D object's shape and appearance (e.g. color, glossiness, transparency, shade etc.). Such 3D objects are stored as mesh in binary format and they have image/x-lwo MIME type. id Tech 4 video game engine (popularly known as Doom 3 Engine) and later versions use LWO format to store static meshes used in games. LWO files may be exported to other formats such as OBJ, STL, and DAE. Tstream Editor Studio, a text processing and translation software uses LWO file extension to store translation packages. Such LWO files use ZIP format and may contain translation proposals, notes, and PDF files.

How to open an LWO file

You need a suitable software like LightWave 3D to open an LWO file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LWO file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LWO file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert LWO files:

  1. LightWave 3D by NewTek
    See the previous paragraphs to learn more about the main application. LWO files are often referred to as LightWave 3D 3d images because this type of file is primarily created or used by this software.
  2. Tstream Editor Studio (translation package) by Xplanation Language Services
    Tstream Editor Studio is a centralized translation workflow system that integrates project initiation, quotations, management, terminology control, translation memory, and other activities into a single process. The LWO file used by Tstream Editor Studio is a ZIP file containing translation proposals, terminology provided by the customer, notes, and PDF documents. This file format is classified as Compressed.

LWO file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our examination of the LWO files comes to the following conclusion:

The LWO file ending mainly uses a defined LWO format. The following file formats are most commonly found in LWO files:

The remaining 5% of all LWO files are files with no common format. These files are often connected to cubesat, generic, nissan, fermi, glast, jwst or pick. Drag & drop your file here to see the file format and a preview of your LWO file!

How to solve problems with LWO files

  • Associate the LWO file extension with the correct application.
  • Update your software that should actually open 3d objects. Because only the current version supports the latest LWO file format. Search, therefore, e.g. on the NewTek manufacturer website after an available LightWave 3D update.
  • To make sure that your LWO file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
  • Click here to open your .LWO file online - secure, fast, and no downloads needed.
