Sorry, missed that.

Tried it with that version. No problem.
What I did:
- I chose one of the prefabs, the Torus, placed it in the top view(but that shouldn't matter),
- then I chose randomly some polygons
- --> Edit --> Create 6-sided mapping, chose any of the sides, click okay
- open the Skin Editor, and there is the first part of the triangles
- repeated this randomly with other parts with the same parts and different sides, whatever I did it works like it should.

You can download the free Lite-C. It includes a newer version of MED and test it with that one.

Maybe its the model then?
im getting mixed results with same model when it has more groups and when its just one group.
Anyway Ill give new one a try then and see what happens.

I had similar problems with importing X files into MED 2-3 years ago, everything should of had be ok but it wasnt. Ended up getting about 5 import.dll from conitect until it was bug free and then it worked.

New MED from Lite-C demo works just fine

Cant use it tough, its not paid version.

Crap, crap, crap.

Thank you for help papen.

Try to ask a developer in the bug section.
