Interstage decoupler will consist of the following:

• Bottom Node Decoupler
• Procedural and adjustable fairing (height, top diameter, bottom diameter, straight-height/taper start)
• Top Node Decoupler
• Ullage/Retro rockets (depending on how it is installed)(can use two if you want both retro and ullage rockets)

Plugin done
Model geometry first pass/prototype is done (no uv/etc)
Model texture not even started

Oh joy!!! 💯

Part is working in dev and will be available with the next update. Models/textures will likely still be WIP.
