adding 3D clouds would be extremely easy and there are quite a few ways i could go about doing it.
You're stupid.
he has a point though
Oh also.
I had a realization today.
it does three searches of the entire area you set, then on one of them it loops the amount of times you set as the expansion loop parameter.
xyl+2xy = pp being the total amount of cells processed.
Keep that in mind when generating! :D
128*128*10+2*128*128
163840 + 32768 =
196,608 cells processed total. Surprisingly, at that rate it doesn't lag much at all, probably since it's mostly dealing with abstract stuff.
ALTHOUGH, there's also the case that I've my math wrong.
EDIT:
I also plan to make a feature where you can save the cloud layer generated, but I may not since that's pretty silly.
