Questions

Are materials and textures kept?

Colours and texture coordinates are carried over when 3DM supports them. Texture images are kept for formats that can hold them.

Will my model be upside down?

No. OFF and 3DM may use different "up" directions, and we rotate the model so it stands the same way in your software.

Are my files uploaded?

No. The conversion runs inside your browser.
