Structural Beams and multilateral export

I finished creating some beams to add the structural elements to the environment. I decided to create 3 different sizes so customization can be done with out the need for copying and pasting heaps of pieces which I've decided I will do with other simpler pieces, such as the floors and curtain wall pieces.

While creating the beams I added some variations to them such as ropes hanging down using the same method I explain in an earlier post. The rope texture how ever was created in a different one to the structural pieces in decided to use two different materials that reference the different textures saving me the need to add the texture to the "Structural Pieces" Texture Atlas.
