The Static Geometry Object is one of many Helper Objects:

The instanced geometry object is a volume that contains entities that are rendered efficiently using shader instancing.

All entities should be contained within the volume of the instanced geometry object, attached as child nodes.

The instanced geometry object is implemented as a NURBS curve list. To modify its settings, the custom parameter set nested beneath the NURBS curve list object must be selected.

• Width/Length/Height - The dimensions of the instanced geometry object, in world units.
• Batch Count - The number of batches.
• Cast Shadows - Indicates whether the instanced geometries cast shadows.

Other Settings

The instanced geometry object color can be modified with the object's Wireframe Color setting:
