fpsc creates a 3d-map out of the levelsegments and statics when building final game. so you should find the levelmap anywhere inside your ready-build gamefolder, but i dont remember how it is called (wrong machine atm).
but someone else around here will tell you/us, i am sure.
EDIT:
ah, got it (quote by REDEYE, thanks buddy):

Quote: "Extracting the static of world of FPSC to use it for other purposes:
FPSC saves a dbo file (for static level only) to use it in the test game build or final game build.
If you test your level and then go to the fpscreator folder (do not click OK to test level just open your file explorer and go to the fpscreator folder) then go to -> files -> levelbank -> testlevel
universephy.dbo is the physics file, which you dont need as you cant import that into your Fragmosoft project.
But what you do need is universe.dbo. This file holds all data for your static world. You can import that file in Fragmosoft. And after that export to .X , .OBJ or any other format.
If you want that your static light maps will be included also, make sure you have the lightmaps folder, which is located in the same folder as universe.dbo, in the same project folder as universe.dbo. So it can be retrieved and applyd by fragmosoft.
If you want that your textures will be included also, make sure you have the universe.dbo parented to the texturebank, so fragmosoft is able to retrieve the textures that universe.dbo asks and apply it.
