Right now, STO uses one generic interior for all ships, so you won't see any custom rooms except for the bridge. With luck, we'll someday get full interiors which are specific to the ship type, but I don't believe it's going to be any time soon.
Actually we're more likely to get custom interiors we can edit ourselves using the same tools for environment editing that exist in the foundry. This is of course even better, since if you want to go totally canon, you can do that, and if you don't, you don't have to. Win for everyone.
...seriously guys, the default interior only got released with Season... 2 ? 3 ? because the Forum was pushing for a release, even if it wasn't ready.
I would argue that the interior size should be limited (or expanded) as appropriate by the ship class you're using. Huge interiors wouldn't work with small ships anymore than small interiors would work with large ships.
Ultimately, this could probably be done in a fashion similar to: Light cruisers/scout ships have small interiors, medium cruisers/science vessels have medium interiors, and large cruisers/carriers have huge interiors as options.
Pursuant to that logic, being able to select a theme appropriate interior (based on that size) would be another option. The only variables needed to be saved for each ship would be 'ship name' (for the dedication plaque) as well as the theme style.
This would kill 2 birds with one stone: immersion as well as relative 'realism' of the interiors vs the exteriors of the ship.
Well like every Escort the Defaint gets a little lack of love.
Still wondering what happened to the panels to the right and left of the Defaint-Bridge.... there is a pre-release-video of STO where they actually ARE on the Bridge, but the Bridges ingame to not have them.
Also the ready room is positioned wrong on the Defaint-type-Bridges.
I mean if you stand with the back to the view-screen Turbolift is on the right, the ready-room on the left side with a Window to the right side.... psitionet that way that window should.... show the Turbolift.... or well... other parts of the interior, not stars since its positioned towards the ships INSIDE parts not leading outside. Don't really get how that happened....
