VirtualSite, I think one way too look at is like this: When you sell your Photoshop document, you are not actually selling any Photoshop software. You are just saving it in Photoshop file format. The client has to have purchased Photoshop to view the file format. You haven't sold them any of the Photoshop program. 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. For example, say I make an obj file using the components of Posette. One would not have to have Poser to use an obj file. You could load it directly into 3DMax, for example. In this case, you are selling part of the original code, which doesn't belong to you. That is why people use stuff like the Objaction Mover, to avoid the problem of selling stuff that doesn't belong to them. Does that help at all?
