Transferring textures between Gen 2 and Gen3 - what is the best way?
Another question about that old annoying problem with Genesis 2 Textures and Genesis 3 Figures. I found several ways to make Genesis 2 textures usable on G3F - at first, the Blender-baking way (I've read the PDF tutorial from here - http://www.daz3d.com/forums/discussion/59665/tutorial-converting-textures-from-gen2-to-gen3/p1), and Blacksmith 3D Texture Converter, described here - http://www.daz3d.com/forums/discussion/66645/m4-genesis-g2m-uv-s-for-g3m-solved-with-new-solution-07feb16 , and Legacy UVs for Genesis 3: G2F (https://www.renderosity.com/mod/bcs/legacy-uvs-for-genesis-3-g2f/113284), which work with Geograft shells of G3F, UV-mapped as G2F or V4. As I understand, Blender must make real texture maps for G3F or G3M from old ones of G2F or G2M. What does that Blacksmith 3D Converter - does it make real texture maps or additional UV sets for G3F or G3M? If I understand it right, it can transfer textures between DAZ and Poser native figures (eg from V4 to Dawn), and even from M4 to G3M) as Windamyre wrote in that thread. Can it be used to transfer textures vice versa - from Genesis 3 Male to Genesis 2 Male, for example? The same with female figures. Ii not, is it possible to create UV-set of Genesis 3 Figures for old Genesis 2 figures in Blender or another program? It seems that Legacy UVs by Cayman Studios use namely UV sets very succesfully. How to make such geoshells with UV sets by myself, if I have G2F clone (shape) for G3F and vice versa, G3F clone for G2F? In some thread about V4 to G3F transfer I found an inspiring phrase - "This is about the same thing I did in C4D VAMP (I had G3F and G2F matched both to G2F default shapes and transferred UVs from G2F", - does it mean that creating an additional UV-set for G3F and G3M is possible? It would be much simpler than full baking process in Blender. What is the best way and tool to do it - Maya or Blender and how to bake textures vice versa, if I want to use some new excellent textures for G3F on old G2F characters?

Blacksmith3D works the same way as the blender method, in that it creates new texture files based on the G3F UVs. If you are unfamilar with blender, this is probably the easier route with this approach, although of course, blender is free. As far as I am aware Blacksmith3D currently can convert M4 to G3M (and I assume vice versa) and V4 to G3F, but not directly between G2M and G3M or G2F and G3F, although that could change in the future.
I have the legacy UVs product to give G3F the G2F UVs and it works very well. I have no idea how easy it would be to create your own geografts to exploit the same method, but I suspect it would be very hard. If it was easy I think Cayman Studios would have already released all the popular UV sets for G3F and G3M.
Oh, thanks for explanations! I hope Blacksmith3D will have those important addons for Gen2 to Gen3 conversions. Though it would be very useful to convert V4 to G2F and M4 to G2M. So far, if to use Blender or Maya for conversions, is it possible to make backward conversions from G3F to G2F or not? I feel, if Genesis 3 Female has the clone of G2F and shaped as G2F, there shouldn't be much difference from the forward Blender method, but I am a Blender noob and there may be some "underwater reefs" with different UV mapping. Someone had problems with nails and eyes of G3F and with jagged seams after forward conversions. How to exclude all odd parts like mouth, eyes and nails from the conversion process and transfer just body and head textures in either direction? Which tool is easier to use for this purpose - Blender, Maya, or something else?
I can not see any reason why you could not use Blender to move a skin from G3F to G2F, but I know even less about Blender than you (I have never installed it). I suspect Blacksmith will give you the easiest conversion, unless you are familar with Blender and/or Maya. People that have actually done the process can give you a better idea than me. I normally prefer UV mapping when it is available, and with Cayman Studio's product I can get a G2F skin onto G3F with 3 clicks inside Daz Studio, so none of the other methods will get even close to that in ease and speed.
