Hey Stu, Correct me if I'm wrong but couldn't they just exported to .PNG, .tif, .bmp for 2D format , and I think if you have Pro Sketchup you can export 3D models to various file extensions like .3ds and .dxf etc.. But I doubt these work in GameEx. I also think .eps is also supported in sketchup. If using sketchup, open the model, then file -->export -->2D model, and save as. PNG for example and these will show in GameEx.
