Industrial Building HDA - Houdini

I made a HDA for industrial buildings to be scattered in the backround of an undisclosed project. This might be the hardest thing i've made in Houdini, a lot of code and trial and error went in to making this and the end result isn't by anymeans amazing but i'm quite proud of it. It works flawlessly in Unreal engine to get some variantion in the background.
Very cool to try out making an HDA to be used in Unreal Engine, unfortunatley i can't show you anything from Unreal besides one simple screenshot due to the project still being a work in progess.
