Any easy way to convert to UDIM

in Technical Help (nuts n bolts)

Experimenting with using Daz content and Mudbox.

Genesis 3 uv tiles use UDIM, so that's easy... but most other stuff doesn't.

So is there an easy way to convert stuff? Ideally few steps and not requiring software that costs a huge amount

    ... holy poo, that worked.

    Ok, so I just used Carrara, moved one surface over a bunch. Now, I did it really imprecisely and figured I'd have a struggle to get things lined up.

    Nope, imported to mudbox, everything lines up fine. I ... don't know how or why, but hey, works is works.

    Spoke too soon. Tried to move things so there were three tiles in all... and it totally didn't work.

    My guess is that it will work so long as each tile is within the proper tile range. But if isn't... thblfft.

    sigh. This shouldn't be this hard.

    Ok, yeah, new test confirms that. So long as I manage to (mostly flying blind and with clunky controls) get the tiles within bounds, they snap into place, essentially.

    Ugly, but it's something.

    What figure did you need it for? If it's one I have, I can do it easy enough in Blender and create a daz uv set for it.

    Well, I want some freedom to range about.

    I was trying it out on Daz Horse 2. May also want it for Genesis, possibly G2F and G2M

    The horse I don't have, but the others will be easy enough. I already have one for G2F I've done before, but I'll need to double check it before passing it over since I don't remember if I fully finished it (she had some rogue verts unattached to anything so need to make sure I've already accounted for those).

    /edit
    I had originally planned on doing a product of udim conversions, but with uv tailor in the store, and the figures being older, there isn't much point, so once I get them done I'll throw them up on ShareCG. Probably some time tonight or tomorrow (I haven't been off work long atm and I'm exhausted, but have the day off tomorrow lol).

    Just so you know I haven't forgotten. Took some time to whip up a quick and dirty script for blender for faster importing/exporting, but I'm working on these. Here's Genesis Base Fem in Mudbox from a DS export.

    You're welcome! Let me know if you run into any issues. You may get some weird errors on import to Mudbox about incomplete uv sets or degenerate faces- there's nothing I can do about these as these stem from issues left behind when the figure was created to begin with. Just click to keep the mesh.

    Thanks for doing that!, but now I have a question: Isn't the DazStudio Texture Atlas used for this sort of thing too? Or does it unstack when loaded, and restack when it's done?

    cheers,

    Last I checked, Texture Atlas does not read UDIM at all. UV sets have to be "collapsed" - also the render engine, shaders used, etc. cannot be set to Iray.
