ON Titan, we have obviously the thick "brown haze" at 200km, and the Methane clouds at ~10 km

so we have 2 sets

So on out .ssc, can we have multiple cloud sets, so that when were on the surface, we can see them?

something like this...

Atmosphere {

Height 500
Lower [ 0.477 0.367 0.211 ]
Upper [ 0.96 0.805 0.461 ]
Sky [ 0.3 0 0 ]
Sunset [ 1.0 0.6 0.2 ]
CloudHeight 220
CloudSpeed 65
CloudMap "titan-clouds.*"
CloudHeight 10
CloudSpeed 65
CloudMap "methane-clouds.*"

}

You can, but not in the way you show. The way to do this is to define an
invisible sphere with the exact same orbital parameters as Titan, and then
define the second atmosphere for that one. Then, the two atmospheres will
be rndered on top of each other. In fact, i have done this in my Postcards
add-on, to facilitate the upper blue layer:



... Of course this technique is headed for the junkyard now, ref the intriguing
experiments going on here: http://www.celestiaproject.net/forum/viewtopic.php?t=10116

I saw that thread, and got some "updated" info for Titan... thx

but going to the 'old way'

I guess

Atmosphere 1 being the main planet

Atmosphere {

Height 500
Lower [ 0.477 0.367 0.211 ]
Upper [ 0.96 0.805 0.461 ]
Sky [ 0.3 0 0 ]
Sunset [ 1.0 0.6 0.2 ]
CloudHeight 220
CloudSpeed 65
CloudMap "titan-clouds.*"

}

and atmosphere 2 being the unseen ghost. The spheres radius would be say 1 km radius less than the main planet, so one never sees the "ghost" underneath

Atmosphere {

CloudHeight 10
CloudSpeed 65
CloudMap "methane-clouds.*"

}

Is this basically the technique you speak of?

Yes, though the size of the "ghost" is irrelevant, as long as it is less than the upper atmosphere layer: you can define it as a CMOD model, and use an invisible (100% transparent) object. Then it will be invisible even if the radius is larger than Titan??s.

Ah, ok, cool. Thx for that tidbit..
