Propane Tank - Shader Breakdown

Having learned a lot about Unreal Engine shaders over the last year I wanted to challenge myself to make a versatile propane tank shader that could be used to quickly adjust color, dirt and rust levels to suit level designers needs on the fly!

My goal was to pack in as many fun adjustable parameters as possible while considering both performance and keeping things user friendly. One thing I'm extremely happy with is the use of primitive data. Having unique settings for each instance of the object is super useful, not to mention it limits the amount of material instances needed per unique look to just one!
Let me know what you think and feel free to ask any questions below!
