Transferring UDIM (tiles) textures


I have a high poly photogrammetry mesh (polycount > 20M) with 4 UDIM tiles. How do I transfer these textures to a cleaned up retopologized mesh with single or multiple tile UVs?

R3DS Wrap’s texture transfer node doesn’t support transferring of UDIM textures. I know Mari has transfer texture function, but since my source mesh is a high poly photogrammetry mesh I am very doubtful if it will even open up in Mari at all. Mari just gets stuck trying to load it.

Can anyone help me out? Thanks.
