[GRASS-user] NVIZ failures

Dear All,

The problem seemed to be with where I stored the desired output file, I had originally tried storing it in a sub-directory of my documents file on the Ubuntu system.  It ran as far as generating 361 graphic files but failed to stitch them in to a single file.  When I changed the location to the home folder it ran completely and generated the high resolution ppm file.

I have tried this using both gui's and as would be expected both have identical outcomes.  It may well be something wrong with a file path specification when using the sub-directory as an end destination.

The resulting .ppm file is very large, around 600 Mb, is this determined by region size of simply from the graphics?
