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

Question

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.
