UDIMS RESOLUTION

Yerus

Hi,
What would be the advisable resolution distribution throughout UDIMs considering a game character?
For instance lets consider a character with clothes 'n big gun, which are been separeted from body and face that would have UDIM tiles for themselves alone. 
All of them would have same resolution? maybe 4K? 
Since face is been handled alone, there is no need to double resolution on it, right?
Thx in advance!

Paint in 4k to be save. The TDs will find out if the game will ship with that resolution in thr end.
