Thanks for the quick response, Debbie!

Quote - Unless it's specifically stated how much of a % of changes needs to be done, then any changes done constitutes a change. 

I would think so, too, but then, if let's say, I only change the head texture and leave the body texture as is from the same resource pack, wouldn't that be against the TOU since you basically can extract the base resource? 

Quote - Thinking with my vendor cap on here...... As a vendor using a resource, I would want to make as many changes as possible so that I could feel that it is my own work.  But that gets into morals and ethics.

I agree on that, actually I would go a bit further myself, I would want to make as much as I can myself and just filling in parts I can't do, so I can say it is my very own work. and work it is making a texture... ;)
And of course I wouldn't feel on the safe side with selling of a merchant resource that hasn't been changed muchly. But that is my own code.

Quote - Thinking with my buyers cap on here....... If I were to purchase 3 character packages that all used the same resources, and found distinct similarities in them, I wouldn't be a happy customer.

Actually, as a buyer, I am not exactly happy if a merchant has too many similarities on most of his/her textures (and I tend not to buy from them anymore, I noticed). I expect to get diversity (as much as possible with Poser L) for my hard earned bucks.

Quote - If resources were REALLY used as they were intended to be used, this question would never arise.  A resource is only supposed to be used in bits and pieces, but the way you're stating here, it's not being used that way, and it's a shame because the vendor will suffer because they do not allow their own creative talents flow into the package, so in my eyes, it's really not their creation.

Agreed, but another question arises then: can the vendor of the original pack, the resource pack, do anything against something like this? Or does it come down to what is stated in the resource pack's read-me, f.e. "you have to change at least 25% on the head and on the body texture before you can sell it again" or "just don't sell as is"?

Edited for yet more typoes such as "dell"....
