Maxwell's Fire (Fast interactive rendering) feature is accessed using the Maxwell Fire window. Using Maxwell Fire, it is possible to view changes to materials, environment, etc., interactively as you work with the model. This greatly improves the general Maxwell workflow, as it removes the need to do many incremental exports and test renders.

The plugin’s Maxwell Fire window has been designed to provide this functionality in as simple a manner as possible. As with other plugin windows, it may be used as a floating window, or docked in the SolidWorks Task Pane; see Scene Manger > Options > User Interface > Dockable Fire Window. At the top of the window you will find a toolbar which contains buttons used to control Maxwell Fire:

Command	Function
Enable Preview	Enables and disables the engine; if Cache Meshes is disabled, disabling invalidates the scene.
Refresh Scene	Re-exports the scene, including changes to geometry, then re-starts the render engine.
Save Image to Disk	Saves the Fire-rendered image to disk (the image is saved at the actual rendered resolution).
Enable in-viewport display	Displays the rendered image directly in the viewport associated with the current camera.
Lock to Current Camera	Prevents the plugin from dynamically changing the camera to that of the current viewport.

Additionally, the Fire window contains a context menu, which is available via right-click when Maxwell Fire is enabled. The options here are fairly self-explanatory, as to their respective purposes:

Parameter	Function
SL	Sets the sampling level at which the engine will stop rendering.
Quality	Sets the actual resolution at which to render; for display purposes, the image is fit to the size of the window.
Threads	Sets the number of threads which will be used by the engine (zero means auto-detect).

Using Maxwell Fire

Maxwell Fire functionality is tightly integrated with the plugin Export option Cache Meshes. When Fire is active, the plugin’s behavior is identical to what it would be when Cache Meshes is activated; the reason for this is that it is neither necessary nor desirable that the scene’s geometry be re-exported, unless it has actually been altered. As such exporting an MXS, or rendering in Maxwell Render, when Fire is active requires no unnecessary geometry-export.

As it is the case that geometry changes and changes to material assignments are not currently able to be handled interactively, the question arises as to what is; the answer is: everything else. Namely, changes to materials, changes to environment, render output settings, etc. – these are all fully interactive.
