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.
