I've been working on replacement spine+frame parts for +Winchell Chung
's Orion mod.
Using his blender files as starting points and intending to make a few different sizes, so instead of the regular one size fits all missions, you can choose how much propulsion you need.
I'm ignoring the pre-populated magazine stacks as, although they're great for quick tests, any real mission with Orions will require variable nuke sizes. It's the only throttle available, might as well have some available.
Anyway, although blissfully exempt from textures, here's the spines so far. I'm intending to make a longer than stock spine as well, but at the moment I have a stock length, and a shorter. Final collection will probably be those two, one even shorter, and one longer.
