On the mirroring - yes I have found that it's a strange thing that WILBUR does- flips the bitmap over. I actually noticed that problem when I started on the Big Island (see post at top) about a week ago. I am actually extremely familiar with the Big Island- so noticed that right away. But with MSH- I never attempted to get the correct scale- in my renders I usually exaggerate the vertical scale anyway as it looks more dramatic. It's just that VUE WILDLY exaggerates the vertical scale insanely when you load a DEM. I have a theory that it is because VUE is converting the 16 bit data to 8 bit and the loss in steps causes the wild increase in scale. (?) Even (see new thread at top) Tom Patterson uses some moderate terrain exaggeration for illustration purposes. But thanks for noting the MSH FLIP- I will re-do it- or maybe just FLIP the render (heh!). Glad to have some good, constructive comments!
