FT3 Flat World Raise/Lower Issues

Larathiel

Hi all, just bought FT3 a few days ago and decided to try and recreate some drawings I'd done on paper years ago, but I've already hit a snag.

When I start raising land from the sea with with a brush, lots of isolated pixels appear all around the edge of any landmasses. When I attempt to erase them, it simply 'rubber-bands' land around where I attempt to erase. I even get this outline of land even when painting a lower operation in the center of the ocean (see attachment).

I've tried raising and lowering bias, un/checking soft edge, and other settings, and nothing helps. Any idea what's going on here?

There are lots of techniques but here's how I do it.

The little spots are due to ringing in the cubic interpolation of the editing data. Before you start painting, try setting the whole world to -100 or so (Tools>>Global Lower>> Land Offset with a value of -100). That way, the little blocks will stay below sea level. I would recommend using a selection and Tools>>Global Raise>>Land Offset to get the basic outlines roughed in before painting too much, though.

http://www.ridgenet.net/~jslayton/CGTutorial/index.html has a description of a technique that gets fairly good results by painting a map. Note that these days I would probably use the textured climate shader rather than the image climate shader.

Ah ok, so it's a matter of just needing to adjust my technique then, that's good. Thanks for the pointers, both!
