GIMP can make random world maps out of the box!

It just so happens that I may actually be able to provide that expression. It might take a couple days though.

EDIT: After looking at the expressions, it looks like you are constrained to the size of your image and the result must match. They may not work as I was thinking of doing an Iso map which would require slicing the image.

I just downloaded the Felimage plugin and it's very good. I've been struggling to get noise to do some things and this has sorted out a few problems really nicely.

I've attatched a forest pattern I made using Felimage in less than 2 minutes. It could quite easily be more effective and a better shade of green.

Cheers for that!

Thanks for road testing it Karl! I know that there are many, many options, and it does take some playing to get results you want.

Could you save the preset, zip it up and attach? We might be able to peel this of and make a "Felimage presets" thread

The canvas size will match, so as long as the input is scalled up to hold the desired output, it should be fine. For example if you wanted to map a 400x400 square to a 2:1 rectangle, you could end up with a 400x200 rectangle having blank space above and below....

or am I missing something
