Only for Biomes.

Allows bringing external variables (Points, HeightMaps) into a Biome Graph. You can set-up a Global Input inside a biome, set a name, and from a TreeView, use the newly created port to pass data into it.

The Default Input port inside Global Input allows setting a default value for those cases when you are generating the biome directly in the Terrain Visualizer
