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 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.
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.
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.
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.
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.
If the problems with opening OBJ files still occur even after installing LightWave 3D, it is possible that you have an outdated version of the software.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.
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

You closely followed the steps listed in points 1-3, but the problem is still present? You should check whether the file is a proper OBJ file. It is probable that the file is corrupted and thus cannot be accessed.
If the file is infected, the malware that resides in the OBJ file hinders attempts to open it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the OBJ file is indeed infected follow the instructions below.
If you obtained the problematic OBJ file from a third party, ask them to supply you with another copy. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. It could happen the the download process of file with OBJ extension was interrupted and the file data is defective. Download the file again from the same source.
Sometimes in order to access files user need to have administrative privileges. Switch to an account that has required privileges and try opening the Wavefront 3D Object Format file again.
If the systems has insufficient resources to open OBJ files, try closing all currently running applications and try again.
Latest versions of programs and drivers may help you solve problems with Wavefront 3D Object Format files and ensure security of your device and operating system. It is possible that one of the available system or driver updates may solve the problems with OBJ files affecting older versions of given software.
