Export only UDIM tiles and not by texture set/material group

[smessierobjects]

Taking a crack at a UDIM workflow on a character and I've separated the model into various material groups purely so I can hide visibility quickly in painter (the character has layered attire).  My mat groups don't adhere per UDIM tile, and I have a few groups that share UDIM tile space.  This means I'm exporting split up textures because painter wants to export everything by mat group.  Is there a way to export textures only per UDIM tile?  Otherwise it seems the only option is combining the split textures in photoshop, which is a pretty annoying step when iterating.  Or perhaps there's a better workflow I'm just not seeing.  Please let me know if you need further info!

Hi @smessierobjects,

Thank you for the question.

I think the issue you're having isn't really an "exporting" issue, but more of a "hiding" issue. Instead of splitting the mesh in several Texture sets for the sole purpose of hiding, I advise you to use Geometry masks. This way, you'll be able to hide/exlude geometry and it won't impact the export. This will also have a positive impact on performances.

However, if you still feel like you'd need a "Merge at export" option, feel free to add your upvote to this post, so we can track users' needs.

Best regards,

Appreciate your fast response Cyril!  I do know about geometry masks, but haven't really used them since they were added.  It does seem like the best option to use them instead, so I'll look deeper into their workflow, but it would be nice to have more control over how UDIMs are exported.  I'll add the request to the post you linked.  Thanks again for your help!
