Group Geometry

This 3D Generator The 3d generator of a 3D Layer represents a source of geometry. Read More produces the geometry obtained by merging the geometries generated by children 3D Generator The 3d generator of a 3D Layer represents a source of geometry. Read More .
The shortest way to create a group geometry is by making a selection of multiple 3D Layer A single 3D Layer (3D object, particle system, ect) Read More , right clicking on them and selecting the Group Generators command.
Use group geometry when you want to manipulate your multiple sub-geometries as a single merged geometry that is associated to a single chain of 3D Modifier Modify a 3D geometry Read More and has a single 3D Renderer Displays a 3D geometry Read More .
If you want to keep separate 3D Renderer Displays a 3D geometry Read More for each sub-geometry, use a 3D Group A Group of 3D Layer Read More .
