As regards making morphs for Vickie 2 you need to contact Daz3D and check with them, though they do have some information on their site in regards to this. You can (AFAIK) distribute morphs made with vickie's face provided they have been squished or encoded. I think Russel's RTE Encoder (freestuff here or at PoserPros) does this and there's probably something else that you can use as well. If you run a search in this forum on Morph squishing that should result in some information on how to do it. If you use Mr. Doe's face morphs and make an entirely new face you will need the permission of Mr. Doe in order to distribute that face because your face is based on his morphs, therefore without his permission you would be infringeing on Mr. Doe's work unless permission was given either in the text file or by Mr. Doe. However, if you use a MOR pose for Mr. Doe's morphs then you can distribute that pose file as it only contains dial information and would not infringe on Mr. Doe's work because people would need Mr Doe's face morphs for the MOR pose to work. In all circumstances though it's always best to ask the original creator first before doing anything.
