Yeah, make a surface attributes mask & transparency map but with values of 255 not 0/null. It's a bit of a pain but I've made this work in the past. It seems like the sort of trick I would have instantly added to the wiki/man page/ML, but I don't see it right now (I only had a very quick look). mmm. coming back to me now. have a look around bug #111 r.los on WinGrass- with a 3D view of visibility from a spot in an Italian valley draped over LANDSAT. screenshot is dated 1/1/10: http://bambi.otago.ac.nz/hamish/grass/bugs/rlos_onearth.jpg r.mapcalc rlos255 = "if(isnull(rlos), 255, rlos)" I've still got the nviz state file and mapset's .bash_history if you are still stuck & want to try and recreate what I did. cut from the nviz state file: 7 7 1 1 poly grid_wire gouraud surf*1262344157 map d...@permanent 0 map r...@paolo 0 map rlos...@paolo 0 map rlos...@paolo const 60.000000 unset #888888 0.000000 0.000000 5.000000 ah, ok, that is a second raster surface added 5m above the landsat DTM. let me know if you are still stuck and I'll package up the mapset as a tarball as an example.
