DAZ to Substance Painter OBJ settings -- SOLVED

A year ago I bought SP, transferred a DAZ object in OBJ format, and it all worked great.  A single object (surface) and a single map.  Using some masks and various layers I did what I wanted and reimported the map into Daz with the results I needed.

Now I cannot remember the settings: every OBJ export I do sends multiple surfaces.  When I did manage to export a single surface (default surface) it still gave me multiple overlapping maps, making painting impossible (everything overlaps).

I have spent a day and a half trying multiple configurations of OBJ export, but can't get this to work.  As you can imageine this is makingme crazy.

To be clear I want a single object to paint on, and a single surface map (not the multiple surface-maps daz uses) to work with.  I am attaching a screenshot of a previous file.

Please don't suggest FBX, I've gone that route and the OBJ system is much better for my needs. I just can't get the settings right!

TIA

    Uncheck the material options, at bottom-right. Of course this will work only for items that have a single, non-overlapping, UV map.

    What Richard said. But I think the item you are working on has overlapping UV.  If that's the new female supersuit and its like the male, its overlapping

    SOLVED IT -- I think. :-O

    After a night's sleep and some bad TV I tried it again.  Here are the export settings and what they give in substance painter. The Ultra Bodysuit has (I think) multiple UVs but exporting this way turns everything into a single map.  This map re-imports to DAZ with correct alignment.

    Thanks for the input.

    If anyone can explain WHY this happens it might help the rest of us.

    The material zones are just groups, they have nothing directly to do with the way images wrap around the model.

    In some cases, such as the human figures, the model will be designed to use multiple maps each of which uses pretty well the whole of an image, and there you do need to keep at least one material zones for each map - sadly Substance Painter doesn't, yet, support models like this though it is promised for the 2.x cycle (in the form of UDIM support - the older Daz figures are not set up that way but modifying them would be pretty simple, just a question of selecting all the polygons for one area and tanslating them a whole number of units along the U axis).

    Thanks for your replies guys.

    Unfortunately I just realised I'd been confusing surfaces with UV zones (and some other, even sillier mistakes I won't go into).

    As it turns out the body suit is only one map.

    D'OH!

    Well, I kinda half-solved my problem.  Thanks for the help!
