AutoCAD Civil 3D :: 2010 Won't Render TIN Surface With Draped Image

I'm running into problems with Civil 3D 2010 trying to render a TIN suface with a draped JPEG.

I've inserted a JPEG aerial photo (supplied by municipal GIS services) and applied it as a drape to the TIN surface terrain model. When I go to the 3D Modeling workspace and try to render the scene, the following error message is displayed:

"This scene cannot be rendered. The scene must contain at least one 3D wireframe or solid model object to render."

The DWG co-ordinate system is UTM83-17. Sometimes these issues can be caused by objects being too far from the origin, and I've tried moving everything to 0,0,0 all to no avail. The surface style confirms triangles as being displayed in Model view, so I really don't know what the problem is here.
