MAX2009 to ZB round trip process check, problems

Hello all.
Been banging my head trying to sort out my process. Ive searched and read
through the forums several times over the past week. Apologies for being dense but I need to confirm a few things to ensure I have the process correct. Im so close to getting the round trip down its making me nuts (because it is so fun and exiting) Yup Im a geek.

For MAX2009
1. Base model in MAX2009
2. Export OBJ (quads ect.)
3. Import to ZB
4. Add subdiv levels
5. Sculpt
6. (in this case I did polypaining)
7. Export lowest subdiv to OBJ again
8. UV/Unwrap (in this case using Roadkill in my case (or other unwrapper))
9. Save out of Roadkill as OBJ again
10. In ZB load completed tool, replace lowest level with import UV/Unwrapped from Roadkill (or import back into MAX for UV tweaking then export again then do the replace bit)

At this point when I color->texture what is polypainted gets scrambled like the UV’s are not there, the geometry looks fine. If I UV Check (there are no overlapping polys) I can see the UV seams made in Roadkill/MAX. Could it be if I used GUV or AUV tiles early in the ZB process (I may have, not sure) this is what the scamble is (AUV/GUV remapping to new Unwrap, which seems to make sense that would scramble things)

I came accross a thread discussing issues with MAX2009 and exploding verts when importing the lowest level then gouing to highest. One advise in that post to export out of MAX as OBJ then back in->collapse to edit poly->export to OBJ again. That seemed to work fine for geometry but the paiting is shot.

Do I need to repaint it or is this a process issue or perhaps bug in the export from MAX/Roadkill (either or).

Thanks

Update: Just repainted it, same result of course. Just seems odd that when I paint it looks fine, it only goes nuts when I do Col[color=orange]>Txr. So its obvious I am missing or messing up something. Also the two sides do not overlap (UV’s), I intended to make it asymetrical in the end.

Ok found this, will double check this when I get home. Hey thanks me. :smiley:

Perhaps it is the vertex numbers being shot.

Ok, In combination with export out of MAX->back in->collapse edit poly-> back out with OBJ (6 digits of precision)-> back into ZB it works!
