If i added octaves and erosion, it would look better. I was thinking of making something that generated 10 Octaves of Simplex Noise that has been Thermally and Hydraulically Eroded that animals overtime have morphed paths on realistic sides of mountains. Also adding in a splash of 3D Simplex to give it some really nice cliffs. Then I would add something to merge bricks so that it isn't brick costly.But this would take more time then I am willing to spend.
A lot of people want to be your friend
Ohhhhhh pretty love to teh eyes for me *Making mini empires and snow country builds*
Or just stop overusing Perlin/Simplex noise. Seriously.
But how fast is it?
Depends on how overclocked your computer is Oeer clocked to the point where you need water coolents(BRAIN MUST HAVE DONE THAT) - no lagNone - HOLY LAG!
