frankie March 20, 2014, at 11:26 AM: This has been added. The various features can be enabled and disabled by tcl commands. In addition, the ground effects are implemented in the "new_moon" shaders in the shaders directory, so see those if you need to customize them further.

For customization, see "configs/planet2_moon.cfg". The new shaders are set in the "shaders" line for the layer. Be aware that the default is to use new_moon.fs, but if your moon definition includes a bmp_map layer, you need to switch to the commented out line that uses "new_moon_bmp.fs" so that the bmp map layer gets taken into account. Also, in configs/planet2_moon.cfg, the layer line also includes two new parameters for tesselation, which are documented in configs/planet2_earth.cfg.

The tcl commands are as follows:

# To enable the fractal soil and craters for close up views on the Moon
 doug.plugin dsp_planet2.parameter MOON.ground.effects_on set 1

 # To enable shadows able to be cast onto the planet surface
 doug.plugin dsp_planet2.option set -shadows 1

 # To enable tesselation of geometry for small craters (if video card supports it)
 doug.plugin dsp_planet2.option set -tesselation 1

 # To enable the planet itself to cast shadows onto itself and geometry (WARNING:
 # performance intensive!)
 doug.plugin dsp_planet2.option set -planetshadows 1

 # To get the current values:
 dsp_planet2.option get -shadows
 dsp_planet2.option get -planetshadows
 dsp_planet2.option get -tesselation 

If you want these effects to turn on and off across all connected clients and be saved in a state, tie the effects to flags on a MOON_EFFECTS node. Add in a node called "MOON_EFFECTS" in your customized planet2_moon.cfg, and then run a script that is something like:

doug.callback add update -nodes "MOON_EFFECTS" -tags "MOON_EFFECTS" {
	if { [doug.node MOON_EFFECTS test "HIDE"] == "1" } {
		doug.plugin dsp_planet2.parameter MOON.ground.effects_on set 0
		doug.plugin dsp_planet2.option set -shadows 0
		doug.plugin dsp_planet2.option set -tesselation 0
	} else {
		doug.plugin dsp_planet2.parameter MOON.ground.effects_on set 1
		doug.plugin dsp_planet2.option set -shadows 1
		if { [doug.node MOON_EFFECTS test "HIGHLIGHT"] == "1" } {
			doug.plugin dsp_planet2.option set -tesselation 1
		} else {
			doug.plugin dsp_planet2.option set -tesselation 0
		}
	}
}
