A `.VRL` file is often simply a VRML world file written in text to define 3D objects and their materials, which you can check by viewing it in a text editor for the `#VRML V2.0 utf8` signature or VRML keywords like `Appearance` or `Material`, since some pipelines store VRML as `.vrl` instead of `.wrl`; once confirmed, you can preview it with VRML/X3D viewers or edit it in Blender, making sure textures remain in their original folders to prevent missing assets, while a binary-looking file may point to compression or a different proprietary format best discovered with 7-Zip or by tracing its origin.

A VRML/VRL file essentially presents a plain-text representation of a 3D scene graph populated by nodes that define structure, geometry, environment, and interaction, making it easy to see objects being arranged with transforms and grouped into hierarchies, while `DEF`/`USE` pairs allow efficient repetition of identical parts so the same mesh or material is applied in different places without duplicating data.

The “things you see” in a VRML/VRL file are typically defined by `Shape` nodes that merge geometry and appearance, where geometry may be basic shapes or `IndexedFaceSet` meshes driven by coordinate and index arrays, and surface style is set through `Material` settings and optional textures, which rely on file paths that must stay intact or the model loses its mapped images and appears gray.

VRML files typically include camera and environmental settings such as `Viewpoint`, `NavigationInfo`, `Background`, and `Fog`, plus lighting nodes like `DirectionalLight`, `PointLight`, or `SpotLight`, which don’t model geometry but shape how the world looks and how users navigate it, and VRML adds interactivity through event-driven nodes like `TimeSensor` and various sensors, with interpolators animating values and `ROUTE` links wiring events so actions like clicks or proximity can trigger movement, rotation, or color changes.

To achieve more complex behavior, VRML/VRL scenes can use `Script` nodes running JavaScript-like code that handles events or calculates values beyond what sensors and interpolators can do, and they gain modularity with `Inline` files plus `PROTO`/`EXTERNPROTO` definitions so creators can assemble worlds from reusable components rather than a single massive document.
