Update: Hi guys, well here is the result of trying to mimic the large curved halls that make up the primary hull (Saucer section)of Trek style vessels.
It consists of only 4 models that are rotated into place, and allows you to easily build a simulation of these decks, including up to a total 0f
"40 usable rooms!"
Each unit has the ability to provide a total of 10 rooms, with adjoining hallways. Just place them in your map and decorate them with prop details (pipes, furniture, Doors, etc.)
They have already been tested in-game, and work extreamly well.

The poly count of each unit is even less than some character models we already use in FPSC, so there is like, zero lag, and no collision issues.
You can easily add hallway sections, to build on these even further. as well as add the prefab rooms such as the "Transporter room" to your overall build. It uses a sigle texture, and is easily retextured to make any style "wall/hall" combination you like.
Hope you like it. More to come....
