Question 1

What are 3DS files?

Accepted Answer

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

Question 2

Are my files uploaded to manuals.plus?

Accepted Answer

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).

Question 3

Perché lo fa URL loading fail sometimes?

Accepted Answer

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