❗World Partition

Massive World works with world partition out of the box but the tool needs to see the whole terrain to work.

The recommended workflow would be to start on a new scene (or convert your current scene to a world partition. Once it is done you can open the area you want to work with and use Massive World to modify it.

Massive World and the stamps will work in world space and are set to not be affected by World Partition, which means that a stamp placed between two sections (one loaded and the other not) will work seamlessly without creating strange artifacts in those transitions!
