I get this error when trying to bake a aiuserdata node to texture: indexed user-data is missing Nrefidxsidxs companion array -- disabling user-data 'Nrefidxs'

It works fine for me. Can u share your baking procedure?

Some work fine but others don't it's very inconsistent.

I select the mesh, set the adaptive metric value to 0 otherwise it crashes.

Plug the aiUsetdata into the shading engine, and select mesh, arnold tab, utilities, render selection to texture.

Select location to bake to; pick a resolution of the map to 1k, 2k, or 4k

and tick UDIM's on.

then bake.

Procedures is okay. Try exporting each mesh separatly instead of bunch. If you need script, I can help u with that. Or may be its ur shading network. See if you could send me a demo file gshankar165@gmail.com
