A .br6 file serves as a native scene format for Bryce, the 3D landscape and rendering software originally developed by MetaCreations and later maintained by DAZ Productions, where it saves complete 3D scenes created in Bryce 6 and compatible versions. Inside a .br6 file you will usually find terrains, skies, water surfaces, atmosphere and cloud settings, 3D objects, textures, and lighting information, allowing Bryce to reopen the environment and render it exactly as it appeared when last saved. Because it functions as a project-level container, a single .br6 file may represent anything from a simple landscape study to a highly detailed fantasy environment with animation and complex materials. However, .br6 is a program-specific 3D image format and not a general interchange format like OBJ or FBX, so your operating system will not provide a standard preview. If you come across a .br6 file outside a Bryce workflow, you can use FileMagic to identify it as a Bryce 6 scene file and, where supported, look inside it before deciding whether to render it in Bryce or request exported assets in a more common 3D format.

A three-dimensional image file is a special kind of file that stores data about a three-dimensional scene so that a viewing or modeling program can render it, let you rotate it, and sometimes animate it. This is not like ordinary image files such as JPG or PNG, which only store flat pixels. A 3D file adds another layer: it can say "there is a point here in 3D space", "these vertices form a polygon", and "this part should use this material or texture". Because it carries structural information, 3D image files are commonly used in game development, animation, visualization, engineering, training content, and modern AR/VR.

Inside a 3D image file, there is usually a definition of the object’s shape, often called the geometry or mesh. This consists of points in 3D space and the faces that connect them, which form the actual 3D surface. On top of the shape, many 3D files also reference the appearance of the object, such as materials and textures, so the program knows whether a surface should look shiny, matte, transparent, or colored. Some formats go even further and include view settings and lighting so the scene opens the way the author set it up. Others sometimes include animation data such as bones, keyframes, or motion paths, which turns the file from a static model into an asset that can move. This is why opening a 3D file can sometimes recreate not just the object, and the viewing setup.

It’s common to see lots of different 3D extensions because 3D didn’t grow out of a single standard. Traditional 3D modeling tools created their own project files to save scenes, materials, and animation. Game developers created leaner formats to make assets load faster. Engineering and architecture tools preferred precise formats designed for measurement and manufacturing. Later, web and mobile demanded lightweight 3D so products could be viewed online or dropped into AR. Over time this produced a long list of 3D-related file extensions, including ones that only certain programs know about. These files still show up in old project folders, client deliveries, training materials, and game asset file opens but appears gray because the texture images were moved to another folder. Sometimes the file was saved in an older version and the new software complains. Sometimes a certain extension was used by a game to bundle several kinds of data, so it is not obvious from the name alone that 3D data is inside. Sometimes there is no thumbnail at all, so the file looks broken even when it is fine. Being able to open or at least identify the file helps rule out corruption and tells the user whether they simply need to restore the original folder structure.

It is also common for 3D files to be only one piece of a set. A model can reference external textures, a scene can reference other models, and animation data can be meant to work with a base character file. When only one of those parts is downloaded or emailed, the recipient sees just one mysterious file. If that file can be identified first, it becomes much easier to request the missing parts or to convert it to a simpler, more portable 3D format for long-term storage. For teams that collect assets from multiple sources, or users who work with old projects, the safest approach is to identify first and convert second. If the file opens today, it is smart to export it to a more common 3D format, because niche formats tend to get harder to open over time.

In summary, this kind of file is best understood as a structured container for 3D information—shape, appearance, and sometimes animation—created by many different tools over many years. Because of that diversity, users frequently encounter 3D files that their system cannot open directly. A multi-format tool such as FileMagic makes it possible to see what the file really is, confirm that it is valid, and choose the right specialized program to continue the work, instead of guessing or abandoning the asset.
