Why did you choose World Machine?

We were making flight games, [and] our editor had the industry standard array of terrain tools ... those tools quickly proved inefficient when we switched to the next generation of console hardware.

How did World Machine improve your work and workflow?

I'd back up a step, and say that World Machine made things possible that wouldn't have been possible at all. The erosion allowed us to create terrain detail that would have been impossible to paint by hand, and the "basic coverage" macros quickly generated masks we could use to generate textures to go along with the heightmap data. We had various macros that would take basic height data from the level designer and would spit out fully eroded and masked out terrains
