Underground biome constructions is a mod that adds new materials to the world generation. These new materials will appear, both between the layers of earth on the surface, and between the layers of stone in the mines. And they will have the same properties and characteristics as the rest of the decorative blocks in the game.

These new materials will allow us to create a large number of new decorative blocks that we can use in our constructions. In addition, each of these materials and decorative blocks will have its stairs, half-slabs and fences, so we can still create more varied constructions, as we can see in the image above.
