No, it's not a power station, it's a building I put together for the animation contest. And I haven't worked on the total or masking out any unwanted rock strata, hence the too stratified background.
And I don't know if the strata can be softened, this is already quite complicated (though it may not seem so), and I strive for a simple, direct way to get nice strata and blocky rock. But it's a frustrating process. My trials often get more complicated after a while and then it's difficult to alter one bit.
