The PrimMiser temp rezzer does more than any other temp rezzer in SL. It does the usual things, of course:-
* Rezzes temporary objects, allowing you to have many more prims on your land than the land normally allows - an additional 50% of the normal prims + 20 (or 500, whichever is the lower number).
* The objects move with the PrimMiser, and are rezzed in relation to the PrimMiser.
* Unlimited copies.
Those features are normal for temp rezzers, but these are not:-
* Protects against accidentaly putting no-copy objects into it and losing them permanently. It refuses to deal with no-copy objects.
No other temp rezzer does this.
* Allows you to pre-position your objects BEFORE putting the Object script into them. The PrimMiser will rezz them in the correct places. With other temp rezzers you have to position the objects AFTER the temp rezzer rezzes them, and while it is rezzing the next instances of them, which can be awkward - especialy when SL is running a bit slow.
No other temp rezzer does this.
* Object groups. You can arrange groups of objects, and rez one or more groups at a time. Using this feature, you can have several different living rooms, for instance, or sections of rooms, and switch between them whenever you want to.
No other temp rezzer does this.
