Extensions are applied to geometry to change how it is rendered. In some cases, an extension will modify its geometry, while in others, it will replace it entirely. The extensions currently available in this window are:
...
Maxwell Grass is a modifier – it adds grass blades to assigned geometry. There is not a great deal to say about it here, which is not covered in the main Maxwell Grass documentation.
Maxwell Sea
As of plugin version 3.0.3, there are two ways of using the Maxwell Sea Extension: by directly assigning a Maxwell Sea Extension to arbitrary geometry, or by using the Maxwell_CreateMaxwellSea command (also available from the Functions toolbar):
...
The Maxwell Volumetric Extension replaces its assigned object with a volume containing a simulation of participating media; it is the host object's axis-aligned bounding box which will define the volume. If an object has both Maxwell Sea and Maxwell Volumetric extensions assigned, it is the Maxwell Sea extension that will be exported. For information on its actual parameters, please see the main Maxwell Volumetric documentation.
