Why my exported UV map is different in size? I did unwrap my mesh which consists of several parts. I did an export using EPS file format, then I applied several images to all the faces in Adobe Illustrator.

Q: Why the export is different in size? What am I doing wrong?
Don't use EPS to transfer UV maps - it only exports the occupied area.
Use SVG instead, it exports the whole UV canvas.
