I'm exporting a character to Substance Painter with the built-in Substance pipeline exporter.
In Substance Painter, I'm using UV Tile workflow.

I create a Fill Layer for the Skin texture set, and set the projection to Fill.

I import the textures (the first of each
sequence).

Substance Painter does not recognize the
sequences, so it won't pull in the rest. Normally, it should recognize it, and big number 5's should appear on each thumbnail.
Obviously because of this, the first texture will appear on each UDIM tile.

The worfklow doesn't work. Is this a known error, or I'm doing something the wrong way?
