Most people prefer a rigid base over a beautiful stylish home. This results in oppressive dark metal castles. This mod will change this by adding a new element: Transparent Metal.
These new walls / roofs have the same durability and effects like their massive counterparts, but they let your base receive the sunlight.
The recipe is only slightly modified. Replace some of the steel of a vanilla wall with crystal – and you’ve got the transparent equivalent.
