When to use
Use it near the start of a graph as an independent source. Branch its outputs when the same pattern should drive both shape and masks.
Example connection:
Perlin Noise · Height → Adjust/Autolevel → Build Map · Height
Notes
Heightfield outputs are sampled at the active preview resolution and at terrain-voxel density during a build.
