SEV Mod questions

[MasterChiToes]

Here's more mod questions...
1) Should the BMPs for the planet models be saved as 24 bit (or 16 or 32)?
2) What needs to be edited besides StellarObjectTypes.txt (looks like one entry for each planet size has to be added there)?

I've begun making some planet textures... using a fractal terrain program. Sweet how the planets slowly turn on the map... never noticed that before.
