What is OBJ file?

OBJ file format is used to store 3D objects created with various design and editing software. Each OBJ file can contain data such as 3D objects including coordinates, texture maps, color palette information, and texture files. OBJ files contain no data regarding the object’s environment. OBJ file format was developed by Wavefront Technologies, originally for a different purpose – it was designed as a file to be used for storing Advanced Visualizer application data.

OBJ and MTL file compatibility

OBJ files more often then not contain references to supporting MTL files which describe object’s surface shading material and relevant data. Each OBJ file can reference one or more MTL files.

Applications of OBJ format

OBJ is a popular open-source file format. It is currently considered the standard format for 3D object/image editing software. It is widely supported, therefore basically all CAD family of software provides means of importing and exporting data into this format. In recent years, with the popularization of 3D printing technology, the OBJ format is gaining in popularity, mainly as the format of choice for multi-color material printing.

Programs which support OBJ file extension

The list that follows enumerates programs compatible with OBJ files, divided into 3 categories based on operating system on which they are available. Files with OBJ suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.

How to open file with OBJ extension?

Problems with accessing OBJ may be due to various reasons. On the bright side, the most encountered issues pertaining to Wavefront 3D Object Format files aren’t complex. In most cases they can be addressed swiftly and effectively without assistance from a specialist. We have prepared a listing of which will help you resolve your problems with OBJ files.

Step 1. Get the LightWave 3D

Install software to open OBJ file The most common reason for such problems is the lack of proper applications that supports OBJ files installed on the system. This one is an easy one. Select LightWave 3D or one of the recommended programs (for example, Adobe Photoshop, TurboCAD, DAZ Studio ) and download it from appropriate source and install on your system. The full list of programs grouped by operating systems can be found above. If you want to download LightWave 3D installer in the most secured manner, we suggest you visit NewTek, Inc. website and download from their official repositories.

Step 2. Check the version of LightWave 3D and update if needed

Update software that support file extension OBJIf the problems with opening OBJ files still occur even after installing LightWave 3D, it is possible that you have an outdated version of the software. Check the developer’s website whether a newer version of LightWave 3D is available. Software developers may implement support for more modern file formats in updated versions of their products. This can be one of the causes why OBJ files are not compatible with LightWave 3D. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using LightWave 3D.

Step 3. Assign LightWave 3D to OBJ files

If the issue has not been solved in the previous step, you should associate OBJ files with latest version of LightWave 3D you have installed on your device. The next step should pose no problems. The procedure is straightforward and largely system-independent
