Maxwell Render comes in two flavours: the preview engine (RS0) and a high-quality production renderer for final images (RS1). Here you can choose which type you want to use for your images.

Channels (Maxwell Options)
RealFlow's implementation of Maxwell Render lets you export several channels with your render. If you want to activate this feature just switch the appropriate channel from “off” to the desired image format. The channel data is only stored with a Maxwell preview (Playback > Maxwell preview) and the "Production" engine selected. When you do s a single render with the “FIRE” engine, channels will not be calculated.
