I had a little trouble making the map with wings3d (do you know any better program ?) but seem to have finally made one, which means I'll be able to texture the hull tomorrow hopefully..
there's still the problem of the sub:
having no torpedo tubes caps or doors
screws
dive planes
rudder
but it's coming along all right ! the great breakthrough for me was to be able to easily make a texture map although not the best I know but it has the sub's number on the side of the tower

.
I still need to make the beta 5.01 stand alone..
I have a tower for the kaidai in stock...
