Just a thought right now but would be nice to know before going through the process.

Is the new Repainting Map option capable of taking a Sub-D uv and texture then transferring the texture pixels to the same object using newly optimized Poly uvs?

Yes, that should work. When repainting you select the source mesh and texture, and it wont matter if that OBJ is a Poly or a SUBD as far as the repainting calculations go.

Unless you're talking about subdivided UVs that is; these are exotic things usually reserved for high-end film rendering in Renderman. Currently UVLayout repaint only works with linear UVs.

ok cool, that pretty much answers my question and is nice to know i have that option.

i have hard surface poly objects with poly uvs brought into to zbrush, but when i subdivide, poly to texture in zbrush creates a thin-bar-like-line near the edges of my textured object.

Seeing this line, and after watching the sub-d uv tutorial, I tried too sub-d my uvs using UVlayout's method on the same object back into zbrush, then discovered it corrected the thin-bar-like-line effect, but also set my uvs up for a not-so-good scenario, because if i want my object for a non-sub-d pipeline such as using polys with normals, i would end-up with a map not usable, the normals or textures wont work correctly unless the object is subdivided in its final destination.

I never sub-d my uvs prior to bringing them into zbrush, this was something i wanted to try to see if it would correct that line-distortion. I think it was one of zbush's many bugs added to recent releases. I'm pretty sure zbrush should automatically subdivide a poly mesh regardless of it's a sub-d object or not and assign the right textures where the uvs are without this line.
