UDIM UV mapping

UDIM UV mapping

Texturing is central to 3D. From UV to UDIM to Ptex, it is easy to think one technology has just displaced another, but the reality is more complex.

UDIM UV mapping has enormous popularity for texturing in the face of much newer systems such as Ptex (which works very well in its own right).

While Ptex may still yet win the texturing heart of pipelines around the world, it has not yet become the dominant force.

you can only import udims , be nice if they could support them in the uv room

[Carlosan]

This is the way 3DCoat supports udims, in other software may be different

i really hope they improve the tools soon , this just isnt good enough , its a jumble sale of tools ... they need an artist working with them on workflow and ux

I'm in modeling room! I've created the uv sets with UDIM names
UVset 1: 1001
UVset 2: 1002
UVset 3: 1003
...

But now I can't found the option to export my objects with UV sets as UV tiles like in the video! How can I save my objects in this UDIM format?

What version of 3Dcoat are you using? I can see it on my side when I try to export object and textures.

[MJonathan]

I'm using 2025.10A, I've created the model and UVsets in Modeling Room.

• Export Poly Object and Export Objects & Textures: Exports my polygroups but in UVsets instead of UV tiles, there are no a dialog with options. I don't have textures.

@MJonathan

Before exporting, you first need to bake the retopo mesh from the Retopo/Modeling room into a polygonal object.

Yeah move it in the Painting room and than do File -> Export. But I do think that this should be option in Modelling room too.

yea a universal menu not specific to rooms would be a lot better , especially if you're looking in one room and the options is in another room , it does get complicated

Thanks guys!! 

And I'm agree! this should be working in every room! If that's the uniq way to export my objects with uvtiles(UDIMS) instead of uvSets, modeling room should be capable to export them with those settings.
