So I have this island/map I am making, I have created some waterways on a portion of the map, the effect I am going for is something like this picture from a river valley in Afghanistan.
What I would like to do is edit my layermask.png with an accurate representation of my waterways so that I may use a "river rock" texture for the area underneath and around the water.
When I export my map as an image for editing in PS, I get this.
The blue portion displayed in the pic is not very accurate and is very pixelated.
So that you can see the difference, here is a pic of what the water looks like when I zoom in in Buldozer
So, what way (if any) can I get a representation of my water areas, down to the last pixel?
