JavaJones: The easiest format to work with overall would definately be an image file, however I'd lean towards tiff or bmp, I have heard rumors of Vue 5's terrain editor crashing when trying to import some png's. The maximum size for a dem import in Vue seams to be about 2048 ish, but since I'm using 3dem I would still definately like to get ahold of the full resolution dem file, so that for wide shots I can get away with the image file and a predetermined Vue terrain (which the editor will allow you to make larger) and for close up shots I can crop out (using 3dem) the area that I need. Thanks a bunch for your responses, that covered everything that I was wondering about (as I too had noticed the slight stepping in the terragen file as well). I'm really jazzed to see what I can do with this in Vue, especially with the 86 lava dome in there (finally) it will be nice to see if I can do some in crater and pumice plain images that actually look decent. As far as model imports go, the best options Vue can import seem to be obj, lwo and 3ds. I'm not sure which of those will provide the highest detail but I would say obj is probably the preferred alternative (if possible). Thanks for providing this data, keep us posted!
