what kind of results are you getting?
So I have it so that:
Less than Cell Average = Water
Greater than Cell Average = Land
Greater than Cell Average +20 = trees
Greater than Cell Average + 40 = Snow
When I only ranzomize the numbers once, there's a little bit of snow, but it looks like crap.
If I average out all of the array values one more time, It looks better, but the snow is essentially gone. I guess this is just playing with values?
I noticed that you have good water and land amount, and your land masses are large and don't have many puddles/lakes within them. Mine looks to have lots of "holes". I wish you achieve your land mass results, while having sections of them have higher "altitude". I followed the instructions on that page pretty much exactly.
