7 Days to Die Alpha 8 Terrain

Hey everyone!

The new 7DTD Alpha 8 has been out for a while now and I have really been wanting to know how they achieved such smooth voxel terrain. I've done some quick googling with no luck in finding out how they do it. Does anyone here know how 7DTD achieved realistic looking smooth voxel terrain and maybe how to apply it to a regular cubic voxel terrain inside of unity?

 

I've done some more googling but with no luck I still couldn't find out how they have achieved smooth voxel terrain. I've seen many algorithms like marching cubes and dual contouring and I've been wondering if they are using one of these algorithms or something similar. Does anyone know how 7 Days To Die achieve their smooth terrain, is it one of the previously mentioned algorithms or something completely different?

 

probably a modiefied version of the "marching cubes" algorithm http://paulbourke.net/geometry/polygonise/

 

Ok, I thought it may be this algorithm but was not 100% sure, thanks for the feedback!
