I created a model made up of 10 boxes, each with its own UDIM number. For testing, if you import this model into the UE editor and create a material from the textures I shared earlier (as shown in the screenshot above), then apply this material to the model, each box should get its own color that matches its UDIM number.

In the end, it should look like this.
