This is my personal "Copyright Policy"; it applies to all my creations (objects, hacks, recolours, lots, etc.), unless differently stated.
1) You CAN'T clone or
modify my creations, without specific permission (cloning an object
is different than creating a recolour, since the clone is a stand-alone
object that contains much of my work...).
2) You CAN'T repost my creations anywhere,
or include my meshes in your recolours.
3) You CAN use all my stuff (objects,
recolours, hacks, and anything) for free; no one is entitled to ask
payment for any creation of mine.
4) You CAN recolour my objects
and post your recolours even on paysites; in any case, you must give
credits to Numenor and put a link to the thread at MTS2 where the
original object can be downloaded.
5) You CAN include my
creations in your lots, as long as your lot is downloadable for
free and *always* will be (this excludes TSR and other "free
rotation" sites). It's absolutely forbidden to include my
stuff in lots uploaded to the Exchange!
In any case, proper credit is to be
given to me.
