The UV map selected was invalid

Hello!

I'm trying to create new UVs.

Now I ran a simple test.

I loaded G2F and exported it with the following settings:

(See screenshot).

To test if that would work, I didn't change anything, I simply clicked "Edit"-"Figure"->"Geometry"->"Load UV Set..." and selected the just exported obj.

Now DAZ Studio asks me to enter a new name for the new UVs, and I entered one.

The next thing I see is the error message "The UV map selected was invalid".

Shouldn't that work?

Does anybody spot what I might have done wrong?

Thank you very much for the help!

    Did you set Mesh Resolution to Base befiore exporting?

    It seems that when I use Base Resolution instead of High Resolution, it works.

    Strange.

    But I wanted to use High Resolution.

    The UVs have to be for the base because the base is just subdivided to get the high resolution figure. If you try to load from a high resolution export, the geometry does not match up. What are you trying to get with "high resolution" UVs?

    The vertex count and polygon assignments in the new UV set have to match those of the basic SubD cage or DS won't know what goes where. Why are you needing to work on a higher resolution mesh?

    Hello!

    I wanted to re-arrange G2F's UVs in Blender.

    I made a simple test, I exported G2F as an obj and simply clicked on "Load UVs" and imported the just exported obj again.

    It worked without any errors.

    However, when I now go one step further and import the obj in Blender and export it again without changing anything, DAZ crashes when I click "Load UVs".

    I did delete the lamp and the camera from the Blender project.

    Does anybody perhaps see what I might be doing wrong in Blender, or is there perhaps a tutorial on this?

     

    Thank you very much for the help!

    Let's keep the discussion in one thread please, so that people can see that some questions have already been asked.

    What are your Blender import/export settings? UVs, as noted above, require the polygons to be in the same order and count in the OBJ imported into DS (as well as the vertices, as required by morphs) since UVs are a polygon property.

    I got it to work with trying different settings.

    Unfortunately I had to re-install Windows before I could store a screenshot.

    But I can confirm it works.

    I tried it with base resolution but still had the error.  Why?

    Can you show what the error message was? Arre you also trying to create new UVs? What version of Studio and Blender are you using? What options are you using for export and import?
