Hey guys, I'm having the same problem that was mentioned a few posts up. I'm on ksp 1.2.2 using orion 0.3.5, I get sound but no animations and no thrust. Definitely looks like I'm using it correctly, I've tried both engines in various configurations. I'm just using the alt+f12 menu to warp to orbit at this point, but nothing is working. I noticed someone mention that installing a constellations pack seems to fix the issue, but I'm on a somewhat limited machine and I'm not even sure what the constellations pack is.
Is this a known issue or is there something I can do to fix it?
