Something I have been wanting to do for awhile. This one comes with some low res images. Im sure this could be modified to make rock type planets and Ice planets.
The results are much better with the high res images I have and I would post it but its 42 Mb. I will post a half size version. Really, all you need is the main texture. The beaches and water wont change much with the larger images.The ice caps get split by water sometimes and Im working on that.
Be gentle with the beach slider, it doesnt take much for that option to start to look bad.
Here is the high res texture used in the example images:
Plug that into the Land Color slot
