Hi. Do you want create new planets or do you want replace the original planets?
Regarding the galaxy generation at start and the AI , is it something to know or the AI doesn't really care about the planet type name?
This is more a question for Ufnv because I do not the answer.
Apparently there is a kind of "starting set" of planets for the game generation, is it modificable without crashing the game at some stage or impairing the AI?
Edit the originals do not crash the game or affect to the IA.
Other point is what do you want edit? the colors or the type? because the type is in PLANTYPE.INI but the colors are in folders which you must extract. The colors are set by some configuration files, in the folder CONFIG.A and they modified the files from the folders TEXTURES\DETAIL and MAPS. These images are black/grey images where you can paint colors for different heights. Ufnv told me this few time ago.

GradientSteps=9
GradientDirection=1
Palette1=0,220,200,180
Palette2=5,179,160,120
Palette3=15,153,143,92
Palette4=25,115,128,77
Palette5=49,42,102,41
Palette6=50,69,108,118
Palette7=51,17,82,112
Palette8=55,9,62,92
Palette9=100,2,43,68
These is the colouring scheme. Note, there are 9 Palette entries (the number defined by GradientSteps).
For each palette entry, first number indicated the "hight" of the terrain it indicated, 50 being the "sea level", 0 - highest mountains, 100 - deepest ocean. Other heights are interpolated between given values.
I will add more to the questions and answers guide soon.
