Planet Package!
Here's a planet package I made to answer this particular request: http://forums.sc2mapster.com/development/artist-tavern/4423-planet-models/#p9
It contains 76 planets, actually it only contains one planet model :P but it has 76 textures for you to choose between. To change the "planet" all you have to do is rename the whatever texture you wish to use so you can import them to the editor. Better instructions inside the package.
The package is rather large so you can contact me to upload a single planet or give you the textures at least.
I take no credit for the diffuse textures, all of them you can find at www.filterforge.com, the rest (normal maps, model, renders, stuff) was made by me.
Enjoy it!
Great pack, this will be really useful down the line :D
But I think a lot of them need some cloud cover.
An interesting method I saw used for that once was in some Wc3 models, where there was the sphere, but then there was also a second sphere that went around the planet. The second sphere was the clouds, and they rotated a bit faster than the planet itself, which really really added to the realism, and made it look really nice. :)
It would probably be a nice addition to the model.
