Hi!

In MED select all (the parts)
select in Edit menu (atlas mapping)..your choice
In the skin editor select again all the parts (just in case)
place the mouse pointer on the paintbrush (most right)

Your model as a green skin
It can now be exported to a paint program
Once the painting is done
bring it back with import.

You should have a skinned model.
Hope this helps smile
