Different size crew compartments?

[Cloakedwand72]

Are they’re any mods that add in different size crew compartments? That would be useful for making your own starship replica.

There are lots.  What size/shape are you looking for?

and there is always tweakscale that might help a bit...

Unfortunately, only while scaling down. There's a cap on KSP that forbids scaling crew up.  (or, at least, it was there last time I checked a few months ago)

@Lisias That restriction may have an association with the issue of number of seats in the IVA space (when one exists). If you up-scaled a crew part and CrewCapacity increased, where will the extra kerbals appear? Players might go looking for them and then complain about that, in which case it's good that this restriction exists. Also... "Tweakscaled IVA space." Think about that for a minute.

But, so, KSP should enforce the cap by the numbers of IVA seats. If you mangle the "crewSize" of the part on the prefab, you will be able to add more crew than available seats on the IVA. Assuming the part has an IVA, of course: not all of them have one or just reuse some default ones from KSP - so this arbitrary limitation is pointless.

A pesky pop up warning that "not all Kerbals will be shown on IVAs due lack of seats" would accomplish the same (prevent the user to expect to see extra Kerbals) and would not hinder the modding scene, not to mention saving us the need to brute force our way using Harmony - and this is something that can fire backwards, as make things pretty harsh to diagnose when something goes down trough the tubes.
