World Machine
A procedural terrain generator using heightfield nodes, erosion, selectors, and multichannel output for large landscapes.
Why it’s here
Mountains, valleys, and material masks stay adjustable before height and weight maps move into major engines.
Best fit
Art, animation, audio, levels, and narrative turn mechanics into a believable world.
Before you commit
The free edition has resolution and other limits and the app is mainly Windows-focused; generated land still needs gameplay and performance shaping.
