elevation_value is to create plane of given value (this usaually means
height), I don't know if this is what you want. The error is in
specifying mode (fine, course) which doesn't match the number of
raster maps. Try

m.nviz.image -a ...       to set the same mode (default is fine
resolution) for all raster maps or e.g.
m.nviz.image mode=fine,fine ...

Try it again and we will see
