Probably just take a minute, and most of that swapping connection point values in notepad. Mesh work is crazy-simple compared to messing around with config settings and testing the results - here it'll mostly just be drag-select, combine, throw a minus into the Y value for the two meshes, and export. I'll add it when I next work on this stuff. Thanks! It's feedback that provides alot of the incentive to continue with stuff like this. I'm not exactly sure what you're after here. You can stick the cap on a decoupler and it'll eject fine. The little one just didn't clear in the screen shot because the sequence bugged and it fired at the same time as the lower one, which shoved the payload against the top. ...tho it means the small one can't fit a parachute normally, as my multi-chute adaptor won't fit inside. Hurm, maybe if I... (I could probably make one with an partial collision mesh to 'cheat' around it, tho, if you want) That had been my original idea, but as Jack said, the way collision meshes work right now it's impossible. A more open interior could only be done by breaking it down further into more parts. Spiffy. Nice to see people enjoying my work.
