There's a lot of useful stuff to make stairs, cliffs, and steps with and a solid amount of different shadows. In addition, the object set is accompanied by a path tool that allows you to easily draw any kind of shape: it has no problem of textures glitching out when making a tight curve and works great with the 'fade in' and 'fade out' allowing to make terrains blend more easily with the path.
The only flaw I found out is an issue with tags and sets: both the 'Shadows & Overlays' tag and the homonymous set display as empty and the only way to be able to use any of the objects in the pack is to scroll down the 'All' tab and find them there.
Aside from this easy-to-repair bug, the pack is great and I recommend it to everyone.
