and setup material , put on my UMG & level blueprint. this material made by simple panner node.
I confirmed everything works as intended mobile preview on monitor.

and I build it my mobile Device, At start, it works well. but over time it seemed strangely.
panner didn’t works well. It turns looks like block.

My coworker says, “You can fix it using customized UV”
but I can’t find customized UV in material domain ‘user interface’.
