What is a RIG file?
A .RIG file contains structural data or system settings. The most common type is a guitar amplifier profile preset used by the Kemper Profiler. These files store the exact sound parameters of a physical guitar amplifier. Another frequent use is an animation rig resource file. Game engines like REDengine by CD Projekt RED and 3D modeling tools like Autodesk Maya use .RIG files to store animation skeletons. Other software developers also use this extension. For example, Iterum uses it for a vRigger Design File, and Hidden Temple Studios uses it for an Antibody Model Rig File.
How to open RIG files?
To open a .RIG file locally, you need the software that created it. You can use Kemper Rig Manager for guitar tone presets. You should use Autodesk Maya or a compatible 3D engine for animation skeletons. For specific climbing or rescue rigging plans, use the vRigger software from Iterum.
Best practices and troubleshooting
The most common error occurs when users try to open an amplifier preset in 3D animation software, or vice versa. Since the .RIG extension acts as a container for completely different types of data, your native software will fail if the file belongs to a different program.
Summary
If you do not know the origin of your file, viewer.online/rig analyzes .RIG files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because many .RIG files use the known JSON format, viewer.online/rig can safely open and display them online, eliminating compatibility problems.
