The thing is that these texture (mostly or entirely, i guess), are made for Zbrush
While in this other, instead, the height map looks more like a displacement map: You can see the same happening here in this texture pack: The thing is that in a displacement map, a valour means sinking and the other lifting, but in the second texture group you can see that a black valour(which is sinking), is in a place where in the colour image is not sinking but lifting instead (a lifting flagstone). If not, where should i connect it in the node editor? The thing is that i need to know what does this map mean. At first i thought it was the same thing but after watching closely, they don't seem to be the same (or maybe i'm bad at observation). The thing is that some of these have a displacement and some others have something called 'Height'.
