When you sell your Photoshop document, you are not actually selling any Photoshop software Actually, I am. Part of the PS software code is now built into the document so it can be read. Sure, I can read it in PhotoPaint or Canvas or any of a thousand other paint programs, but it's still a PS-identified document, using PS-identified code. And all a mesh is, is code as well. So I guess I still don't see the difference -- my PS-code written document is no different from a Poser-code mesh. I can take my PS-code written document and turn it into a Canvas-based tiff file and sell that to my client, but if I take my Poser-code document and sell it, it's wrong? Now this is making a distinction between materials that come with the default program, like Posette, and third-party generated meshes, like Vicky... but even that becomes a bit of a grey area, unless there's another program out there than can run Vicky with full functionality aside from Poser. As far as I can see (and I hope someone will correct me if I'm wrong), the animation and joint system used by Poser is fairly unique. So, in essense, everything at DAZ, RunTime, Poserworld, any of the sites we all frequent, are all selling a small part of the Poser code. They have to; there's no way to get around it. So that's okay while this isn't? When you sell a mesh that includes components of the other mesh, a person doesn't have to have purchased the original mesh to use it But they would need Poser to run it with full functionality, right? Sure, you could export it as an obj file, but, again, how is that different from me saving my PS file as an exported jpeg? I'm really not trying to be dense here. It just doesn't seem to be any different.
