The Extended File Support plugin enhances Obsidian by enabling users to view and embed various file formats that are not natively supported. It provides read-only compatibility for image, design, and 3D model files, including Krita (`.kra`), Photoshop (`.psd`), Adobe Illustrator (`.ai`), and multiple 3D formats (`.gltf`, `.glb`, `.obj`, `.stl`). Users can configure file display settings, such as scaling, embedding dimensions, and camera positioning for 3D models. The plugin also integrates with Obsidian Canvas, ensuring smooth visualization across different workspaces.

The Model Viewer plugin adds support for interactive 3D model viewing directly inside your notes using Google's `<model-viewer>` component. It recognizes `.glb` and `.gltf` files in your vault, enabling file previews, tabbed viewing, and seamless embedding via native syntax. You can adjust display settings like height, width, and aspect ratio, or even add multiple models side by side. It supports advanced attributes from the `<model-viewer>` API, such as autoplay, lighting controls, and custom camera positions. When used with the page preview plugin, you can also hover over links to preview models instantly. This plugin is especially handy for developers, designers, or educators working with 3D content who want smooth visual integration within their notes.
