3DS (.3ds) is an older Autodesk 3D Studio mesh format. It can include geometry, basic materials, and texture references (often external image fileс).

Are my files uploaded to manuals.plus?

No. Drag & drop and Browse loads are processed in your browser. If you load from a URL, your browser fetches that URL directly (subject to CORS).

Почему URL loading fail sometimes?

Browsers enforce CORS. The host serving the .3ds (and any external textures) must allow cross-origin requests (Access-Control-Allow-Origin).

Drag & drop anywhere, or Browse to load. Optional: load from URL (CORS required). Client-side viewэ-э.
