Node Reference

This page provides a summary of all available nodes in the Dynamic Dungeon world generator, categorised by their primary function.

Biome Selector	The Filter.** Isolates a specific biome's area into a boolean mask.
Biome Weight Blend	The Arbiter.** Resolves multiple competing weight maps into a single Biome ID map based on which weight is highest per-tile.

Blend

Nodes used for combining multiple masks or float channels using common blend modes.

Node	Description
Layer Blend	The Visual Compositor.** Combines two float maps using standard layer blending modes, similar to software like Photoshop or GIMP.
Masked Blend	The Switch.** Selects per-tile between two float inputs (A and B) based on a boolean mask.
