Join Geometry Node
The Join Geometry node merges separately generated geometries into a single one. If the geometry inputs contain different types of data, the output will also contain different data types.
Note
The node cannot handle the case when more than one geometry input has a volume component.
Materials
When multiple mesh inputs contain different materials, the material slots from each mesh geometry are merged so that the output mesh will contain all the input materials.
Attributes
When merging attributes from multiple geometry inputs, the highest complexity data type is chosen for the output attribute. In other words, if a weight
attribute has a Boolean type on one geometry input and a vector data type on another geometry, the weight
attribute on the output geometry will have a vector data type. The same heuristic is used for attribute domains, the domain with the most information will be used for the output.
Warning
Like other geometry nodes, this node always outputs generic typed attributes. So instead of a Vertex Group attribute, it will create a “Float” attribute on the result, and it will create a generic 2D vector attribute instead of a special “UV Map” attribute. Some other areas of Blender don’t properly handle generic attributes in version 3.0.
Custom face corner normals are also not transferred currently.
Inputs
Geometry
Geometry that will be joined. Multiple inputs are allowed. When the node is muted, only the first link will be passed through.
Properties
This node has no properties.
Output
Geometry
Standard geometry output.
