I think I found at least part of the problem - I tried saving my settings to m.nviz.image and the command saved zexag=0 although mine is set to 0.3, I got 2 when I set it to 2.3. Looking at the gxw file it is also saved z-exag as integer 0. Changing it to FP should fix it. > <z-exag> > <value>0</value> > <min>0</min> > <max>10</max> > <original>1</original> > </z-exag> > > Volumes: > - change of region by g.region seems to be ignored (or I missed something), I > had to restart GRASS with the new region > to get the 3D region for volumes right.

Here is my slice when my res3 is set to 1 - it works perfectly and the new controls are much easier to use http://skagit.meas.ncsu.edu/~helena/measwork/umstead/bank1_08_24_11_DTF_eldiff_timeslice9.png when I set my res3 to higher resolution, the slices do not show up. the image is eroding stream bank, so that is why the surface is vertical.
