Keep going, DSep... i find these planets to be great!
As you may know, i also think Planets are some
key features to add into a fairly complete Mod.
Each of the 39 Races in X-Worlds absolutely needed to have at least "good" *distinctive color-wise and general continental shapes* HomeWorlds and system neighbors.
And, now that i -Majored- the Minors (indirectly) i will also give them that much of a Planet individual feel too.
Wait until you get to the RAW files though and trying to apply some Terrain-Schemes to those - i assure you, the work is complex. Well, unless you DO have a trick or two to share since to me, the normal Bump Maps & conventional Grey-Scales variations never seem to deploy as they really should on surfaces.
