Geometry Nodes Modifier
The Geometry Nodes modifier creates a modifier with a node group which defines its functionality.
This modifier is supported by mesh, curve, text, and volume objects.
- Node Group
A list of the node group's inputs which can have unique values even if the group is shared among multiple modifiers.
If the input is connected to a Field socket, there will be a toggle to switch between using a single value for the input or using an attribute on the input geometry. Using an attribute for input means the value can be different for every element.
The attribute name used by default when using the node group in a modifier for the first time is defined in the node group inputs panel.
The attribute domain and the used to access the attribute is defined by the node the input is connected to.
By connecting a field socket to the group output node, you can create custom Attributes from a Field output of any node in the node tree. The domain of the attribute must be specified in the group node's output properties. Note, this does not work with Instanced Data.
The attribute name used by default when using the node group in a modifier for the first time is defined in the node group outputs panel.
This panel displays information about all custom named attributes used by the node group. More information is available in the geometry nodes inspection page.
