Of course the insolation a planet receives, for the simple case of a non-inclined planet (which I assume we'll be assuming, lacking information to the contrary) scales with latitude, φ as cos φ. Consider a Sudarsky Class III planet just inward of the "habitable zone." You might imagine it would have water cloud condensation at its polar areas. So you could imagine a III-II transition texture, where the polar areas resemble a Sudarsky Class II planet, and the equatorial and tropical region are more Sudarsky Class III. We see something similar going on at Saturn, where the polar areas took on a more Uranus-like appearance. I believe this is from ammonia condensating out of the atmosphere at cooler temperatures but chemistry is really not my thing so I'm very open to being shown otherwise.

Here is a class 2-3 transitional texture derived from Kexitt's textures (which we can use):

Also a possible generic texture for terrestrial planets; it's just Mercury+Venus+Mars:

John Van Vliet, are all your textures compatible with Celestia's license, i.e. can they be used with the standard Celestia distribution?

Nevermind, found this.

The Mercury + Venus + Mars blended texture would be good for all terrestrial exoplanets.

Yes, that was my intent for it.
