so i have this model and i hadn’t realized the poly got so high and im trying to zremesh it with half the count, so i start the remesher and wait for it to load and everything which takes forever cause i dont have a high end comp… but when its done nothing has changed and there is no error message or anything, no undo history either… can someone help me?
try decimating your mesh first and see if that helps.
it actually worked finnaly right after i posted this lol
but for future reference, i know where it is in my tools but what does decimating do?
Decimation Master greatly reduces the triangle count while preserving as much of the surface detail as it can.
wow that is awesome, im super new to zbrush and im still learning all of the tools, thank you for the help 
Decimation is a good suggestion if there are no multiple polygroups as decimation would make one single polygroup.
