Permissions help needed again

ok...I thought I had this straight but I'm confused again.

this is regarding prim items (fountain and fireplace to be exact)

When you set the permissions on the item (and I know you need to rez it first etc), the transfer box is greyed out (but with a checkmark in it). If I click only modify, it remains greyed out (again, with the checkmark in it).

my question: if the resell/transfer box is greyed out with a checkmark in it, does that mean that it automatically defaults to transferable? So that, if I make an item, and enable modify so that someone could change the size if needed, but do not click copy, they are automatically able to resell the item?

I had someone who 'really really wanted' something I had made, I sold it with modify enabled and assumed (probably incorrectly) that they wouldn't be able to resell it. I also sold it for less than the asking price because they wanted it sooo badly and were poor and blah blah. I now find they have the item up for sale for more than twice what they paid for it...double checked permissions on it and it was still modify with the resell/transfer box greyed out.

I guess I'm pretty sure at this point that I need to choose copy and modify and unclick the resell box but just want to make sure I'm right so I can avoid this in the future.

transfer is automatically enabled on items. you need to check the copy box, then you get the option to uncheck the transfer. if copy is not enabled, transfer is.

thanks, live and learn lol

Yes - officially you can ban copy, or ban transfer, but not both. I believe that when the permissions system was set up, they assumed that most items would be just like real-world items (ie, no copy, yes transfer) which is why that's the default. Then, they made a special case for reproducible items (ie, yes copy) which required no transfer to prevent anyone who owned one from being able to set up a shop.



Yes. Granting copy permission will enable you to deny transfer permission. Although, if they have transfer permission only, they can only sell their one copy of the item, and then it is gone.

You can enforce stronger permissions limits using scripts, but this is rather involved.

Right: either Copy or Transfer, or both, must be checked. If you check Copy, then you can choose to uncheck Transfer. If you don't want the next owner to be able to transfer an item, then you can let them Copy it for their own use instead. Different sorts of products are more useful with one or the other permission; the creator has to decide which to permit (or to sell multiple different versions with different permissions).

Now, this gets complicated if a product includes Contents (like a script, etc.). To really have the intended permissions, those Contents must have the same permissions as the containing object. But one can also use this to make an object effectively neither copiable nor transferable: If the object itself is useless without a script that it contains, and that script is useless without the object that contains it, then if one can only be transfered and the other only be copied, effectively the buyer gets one non-transferable, non-copiable instance of the product.

You'll want to consider any scripts in the prim objects too. If you want an object to be copiable, for example, the scripts need to be copiable (rather than transfer) as well so that each copy rezzed will have functional scripts inside.

The unusual case with this is modify. A script can be no mod in an item, but the prims themself be modifyable. Setting the persmissions this way makes it so that the script cannot be opened and looked at by someone else. If you are using free scripts, this is no big deal, but if they are custom allowing mod rights is basically the same as making them full perm. Some one can open the script, and then cut and paste it into their own new script where they can set the permissions any way they would like.

Edit: Yumi and Qie beat me to the punch on this one.

very nice answer thank you I had to read it twice but I think I got it now

Edit: ps, thanks to everyone who answered
