The plugin supports several Maxwell extensions, which generate render elements at render time:
| Extension | Description |
|---|---|
| Maxwell Grass | Accessed via the Maxwell Grass window, this extension produces grass blades on geometry. |
| Maxwell Sea | Accessed via the Maxwell Sea window, this extension produces a sea surface, using Next Limit RealFlow technology. |
| Maxwell Volumetric | Accessed via the Maxwell Volumetric window, this extension produces a region containing participating media. |
All three of these extensions are created by assigning data to a SketchUp group. Their respective windows track the active selection, with changes made being applied to all currently-selected groups. At the top of the windows you will find an item named Selection, which indicates how many groups are selected, as well as the most-recently selected group:
In this example, there are three groups selected, with the most recently-selected one being named "Plane". Oftentimes, groups have not yet been named, in which case, this selection would appear as:
For information on the meaning of the parameters contained in each window, please see the relevant documentation:
All three of these use geometry in their group, and/or its bounding box, along with the transformation of the group, to define how they are created and rendered in Maxwell.
In the free version of the plugin, each extension is limited to being exported for one group. It may be enabled, and its parameters set, on any number of groups, but it will be written only for the first group found during export of the scene to Maxwell Fire.
Be aware that it may be very easy to create extensions which use a great deal of memory, and which may therefore crash the SketchUp process.
