I have my own little brain design on how the warp core within the nacelle is going to work. I've got anti-matter containers lining the pod that feed into an injector that is in turn fed deuterirum through the ball on top which also helps collect stray particles. This will lead into the core which is inside the anti-matter bottles (not modeled yet) and will have a plasma feed line to the warp coils and also back to the ship and secondary impulse engines on the struts.
This isn't something that's going to be on the finished mesh of the ship because there isn't any reason to. Well parts of it will be, but this also lets me make up neat 3D engineering displays for the warp systems.
