Google SketchUp to Unreal Editor Help - Epic Games Forums
Sketchup into Unreal....
You have 2 options when doing this
1. Buy the Pro edition (which is about $500 i dunno), that has the export on it already
2. Get HT3DUT3. Its a plugin which i use that can convert skp straight into 1 mesh of t3d or even a whole world of t3d. Its great.
