FBX Asset Library is an N-panel add-on that provides a visual interface for managing and importing external 3D model files directly within the viewport. It operates as a local asset browser specifically for common exchange formats, allowing you to view and import content without leaving the software.

The tool features an automated thumbnail generation system that creates preview images for your assets. When initiated, it processes files by setting up a temporary scene, framing the geometry, applying a three-point lighting setup, and rendering a companion image. This process includes a progress indicator and handles subdirectories recursively.

The library system supports categorizing content into distinct collections managed via the preferences menu. The user interface features an adaptive grid layout that adjusts to the panel width and uses a cached pagination method to navigate large collections while managing memory usage. The add-on supports importing FBX, GLTF, GLB, and OBJ formats and includes a text-based search filter.
