Interactive Preview panel (FIRE)

Studio includes an interactive preview mode, Maxwell FIRE (which stands for Fast Interactive Rendering), which gives you completely interactive feedback of your scene, rendered quickly in CPU draft or GPU modes.
As it works internally with Maxwell Render technology, it is physically correct and provides outstanding lighting and shading quality.

It is an invaluable tool to help you adjust the lighting and materials in your scene while seeing an interactive accurate preview of the final results. It includes camera effects such as depth of field, motion blur and SimuLens.

The Interactive Preview panel provides you quick feedback during your scene setup

You can use the action buttons to launch or stop the preview either in CPU or GPU mode in the Interactive Preview panel:

Action buttons

You can interactively adjust the materials, the environment conditions, and the intensity of lights or move the camera and adjust its settings.
You can also move objects and lights in your scene whenever you want, although it needs a quick voxelization time to update the scene configuration.

On the main bar of the Interactive Preview window you have the following tools and options as well as the informative area at the bottom:

	Settings.	This button opens the interactive preview options panel which allows changing the Sampling Level and Time Limit for the interactive preview as well as the Quailty level which controls the resolution of the image rendered with the interactive preview.

Preview Options

Sampling Level: This sets the Sampling Level limit for the interactive preview; once the render reaches that SL Maxwell will stop calculating the preview.
Time Limit (s): This sets a second limit to stop the render, this time in seconds. The limit that is reached first will stop the preview.
Quality: This setting changes the resolution of the preview. It can go from 1 to 10. Lower quality means a lower resolution and faster previews and higher quality means a higher resolution and slower previews. This doesn’t affect the quality of the light solution, ray bounces, or anything similar.

Here is the resolution of the different quality levels; the horizontal dimension is fixed and dependant on the quality level, the second dimension depends on the proportion of the camera used. This list shows the resolution of the default camera.

1: 200x150
2: 320x240
3: 400x300
4: 640x480
5: 720x540
6: 1024x768
7: 1280x960
8: 1440x1080
