when i changed to "constant detail" i didn't get the "Digital size" instead i have "Resolution", is this related to my Blender version (2.79) or did i miss something ?
If it is how the new Blender work, does this behave exactly like "Digital size" ?
so far it looks like it's giving me the same result but i just wanna be sure, thanks!
The Detail method changes the detail size/resolution, and their values work inversely. With detail size, smaller values = smaller polygon size. With resolution, bigger values = smaller polygon size.
I go over these settings in depth in this live stream starting around 41:40.
