Map making: Really jagged!

[Jitters]

So I've been making a map, and I've notice my terrain is really jagged, despite smoothing, blur and such. As a test I did a 1% change of pixels and it still made a jagged step, even though they are only one value apart from each other. Watermill has some really smooth hills, and I was wondering how I can make mine really smooth too.

Any ideas?

i think to make smooth hills, you have to use different colors that sort of rangs from light to dark, then put them in a certain order and blur them. if you dont know what i mean heres an example.

couldnt get the picture to load, but anyways.

dark grey, lighter grey. lighter, grey, lighter grey, etc. really close together untill you feel its high enough. Then blur with the rate set at 100%

Even with ample smoothing, stepping can still occur.

Changing the size and height of the map will even it out. The larger/higher the map, the more the height-map gets stretched and thus the more it will smooth over.

Seems to work nicer when I make the map big...however now my map is HUGE!

Change the height of your map maybe? So that it's not so steep.
I'm not sure if I'm picturing correctly what's wrong, but oh well. It's the thought that counts. :3

Nope, making it taller makes no difference, and neither does making it wider, it just makes the steps bigger. I'll play around with some things and maybe it'll work.... I don't understand why watermill is working but the rest are not....

I've generally found that using Blur creates those jagged edges. When making maps "by hand", however, I've noticed that using a soft brush decreases the jagged edges - you just have to use closer or more distant shades of gray, depending on what kind of steepness you want.

Unless you use a 3D Heightmap Maker, like L3TD, you'll always end up getting at least a few of those jagged places.

yeah, I'm still not getting smooth hills. They are all jagged steps and flat on the top...
