Gert, I think I tracked down your problem and sent a submission to Robert. Thanks for helping debug this, you tracking down that it was a problem with the extents made finding the problem much easier.

It seems to have something to do with the extent of the DEM and the extent of the textures. I am guessing it has something to do with the changes Robert did regarding the cases where data crosses the dataline.
