By upgrade, I mean the fact that when you research certain nodes, parts get different stats. By module, I mean the part of the .dll that adds the upgrade functionality. What I am asking is if it is possible for me to make a different .dll which only adds the upgrade modules from the original KSPI .dll, and if so, how I would go about doing it. I know nothing about .dll files, but my guess is that it might be possible to de-compile the .dll, find the bit that does the upgrading, and re-compile just that part of it. Sorry for wasting your time if it's not possible and I'm just blabbering.

I don't know much about Kerbal modding, but I would have thought it possible to make a mod which only adds the relevant upgrade modules to KSP so the necessary lines could be added to stock part configs.

I was wanting to apply some of the part upgrade mechanics in Interstellar to vanilla parts in KSP. I am assuming this is not a vanilla feature, and so I would need Interstellar installed for it to work, correct? Also, is there any way I could siphon off that part of the mod to make a smaller mod that just does the upgrade mechanics for personal use? (I wouldn't distribute it without permission). It is a feature that I would like to have on my less modded playthroughs without all the parts and complicated other mechanics. Thanks!

I think I was just being thick; I thought setting it as an airlock would make it import an airlock texture. Looking at the command pods, I can see this is not the case. I just needed to actually put the texture on, then it would show.

I have made a basic part that has an airlock and works, following this tutorial: http://wiki.kerbalspaceprogram.com/wiki/Adding_Airlocks_and_Ladders_to_Parts. It works, but the airlock and ladders are invisible. Any help?

This sounds good, but is there some way we can have an unmanned Science Lab? Maybe with a lower transmission boost multiplier?
