nviz elev=dem color=landsat

see the ps.output addon program for one way.

otherwise with ps.map you have to compose with d.shademap, then use
'd.out.file format=geotiff' with desired rows,cols and then r.in.gdal
the composite image back in. then you can use it with ps.map.

d.shademap only runs with 2 rasters (but you can overlay other d.*
commands too).

ps.map limits you to a single raster map, or RGB 3-raster group.

nviz will let you load multiple rasters. in addition, most "Surface
Attributes" for each map can be another raster map.

(I've sort of lost track of which module(s) this question is about)

you can't get them to work at all? or e.g. the Arrow falls on top of
the word "North" etc. they are generally functional, but are still
rather clunky to use.
