Reply To: need help understanding sculpting detail steps 2.79 for a beginner.

this might not help much but you are using constant detail that’s why you go up not cause of  a newer version of blender and a lot of courses here use relative detail 

also the higher detail you have  the harder it is to change it so lets say you are making your hands and you are at 90 detail  well it’s going to be a lot harder to smooth out something you don’t like so you would have to lower your detail  and that might not even help much if the detail is to high 

but here’s  some examples like if you didn’t like the shape of your finger nails or if your knuckles are to high it’s going to be a lot harder to smooth them out and make the old ones  unnoticeable  a better example though would be eyebrows 

here’s a pic i did of Melvin  i did the same things to the both of them just the one on the left i used a higher detail brush   hopefully someone more experience can explain better
