Warning Node

The Warning node outputs a custom message that is displayed when the node tree is evaluated.

This allows node groups to communicate expectations, assumptions, or error conditions, such as required input ranges, missing data, or unsupported configurations.

By default, warnings are propagated through parent node groups. This behavior can be controlled with the Propagation Geometry Nodes setting on each node.
