if i select some poly on level0 and create a selection set im able to hide the set via the object list…
but on a higher level nothing get hidden… and if i turn it back on the level0 set will shown..
now level0 and level1 are on the screen at the same time…
I am just figuring out about hiding face selections—I do it like so.
I make a selection set for the particular level I want to sculpt, usually a higher subdivision level—this selection set won’t be maintained on other levels.
I make a named selection set.
I go into face mode.
Then I used the DISPLAY/HIDE UNSELECTED --- I don’t use the eye icon in the object list because it doesn’t really seem to do much.
A face selection, as you go up and down the subdivision levels, may not stay consistent, maybe because of face count ... but I just go with what seems to work.
I’d love to see some official info on this topic.
