NOTE: THIS CAN ONLY BE USED ON LARGE FEATURES, NOT LITTLE MICRODETAILS
I recently discovered a simple and fast way you can locate subtle imperfections. For instance, something JUST ISN’T RIGHT on the shading of your bust’s cheek. You can’t quite locate it.
The solution: You can use the smooth brush on ZSUB to sharpen, rather than smooth features. If you do this on a supposedly flowing surface, it will make many of the small imperfections stand out VERY MUCH. Then, simply undo, and fiddle till it’s fixed.
Hope this helped someone!
