Castle of the Bloated One Megadungeon....

To what 3D formats does Sketchup output? I'd love to see these fully-textured in a 3D environment.

Thanks for the rep!

From Sketchup's help site:

Sketchup Basic (the version I'm using)

You can export 3D models to other programs in several 2D and 3D formats:

Export 2D images of your models.
JPEG image (.jpg)
Portable Network Graphics (.png)
Tagged Image File (.tif)
Windows Bitmap (.bmp).
Export your files to COLLADA (.dae) format for use in a variety of different 3D programs.
Place models in Google Earth. You can place SketchUp models in Google Earth by using the "Place Model" command.
Export a Google Earth file directly in KMZ format.
Share SketchUp models to the 3D Warehouse.

SketchUp Pro

In addition to everything you can do with SketchUp, using SketchUp Pro you can:

Export in additional 2D formats:
Portable Document Format (.pdf)
Encapsulated PostScript Format (.eps)
Epix (.epx)
AutoCAD (.dwg, .dxf)
Export 3D models in additional formats:
3DS (.3ds)
AutoCAD DWG (.dwg)
AutoCAD DXF (.dxf)
FBX (.fbx).
OBJ (.obj)
XSI (.xsi)
VRML (.vrml)
Export animations and walkthroughs as MOV with the Mac version of SketchUp, or export AVI files from the Windows version of SketchUp.
