No it's not that!!!
Kerkythea can load the format obj of Moi!!! :)

JUST PUT THE OBJ FILE IN THE FOLDER "MODEL" OF KERKYTHEA!!!

There are some bugs in Kerkythea managed path file!
Another one is about accents of names of folders!!! (for french it's terrific :(
You must save also from Kerkythea in path without names with accents!!!
