- Time: Time is the maximum time Maxwell will render before stopping. As it is possible to stop Maxwell at any time, it is generally best to leave this set to a higher number of minutes than will be necessary to obtain a clear image.
- Sampling Level: Rendering will also stop if it reaches the specified Sampling Level (SL), if it is unable to reach the specified SL before the Time has been surpassed.
- CPU Threads: This parameter specifies how many threads will be spawned by the Maxwell render process. Setting this to zero will cause Maxwell to auto-detect and render using all available CPU resources. Setting the number of threads to [CPU physical cores – 1] represents a good trade-off between rendering speed and machine responsiveness, in case the machine must be used for other purposes while rendering.
- Extra Sampling: Enables additional sampling of specific regions within the rendered image. Click the corresponding edit icon to define the regions. See Extra Sampling.
In Maxwell, the image is regularly updated during rendering. You can terminate a Maxwell render at any point in time, and save the resulting image at the time of render termination. For single image renders it is generally better to keep the sampling level limit high (the default of 25 works well); the render can always be stopped at any time if the result is satisfactory with a lower sampling level. Also, renderings can be resumed (processed further) later, by opening the MXI file in Maxwell and clicking on Render. See Rendering in Maxwell.

- Multilight: Enables Maxwell’s Multilight. Multilight is a unique and very useful feature that allows you to interactively adjust the intensity and/ or color of the emitters in the scene and to alter the ISO and shutter speed during rendering or after the render has finished. The adjustments may be keyframed and animated over time, and a sequence of images can be saved. With Multilight, with just one rendering you can save different images of the same scene under different lighting conditions or make lighting animations. Multilight will result in significantly larger file sizes and increased RAM usage, especially when the Color option is enabled.
- Export Point and Cone lights: Globally enable/disable export of form•Z point and cone lights. If disabled, these light types will not be exported, regardless of the ‘enable’ setting on each individual light.
Geometry
- Export By Layers: All objects on each form•Z Layer will be merged into a single object in the MXS. Useful when scenes will be further worked in Maxwell Studio.
- Allow Maxwell Studio to Export Geometry: This option to allows the MXS file to be exported from Studio to other 3D formats later. If this option disabled, the geometry from your form•Z project is protected.
...
- Override: Override all project materials (except emitters). Select: Select an MXM to use as the override material. Leaving the path empty will use a generic, medium-gray material as the override.Click the corresponding edit icon to select an MXM, or leave the filepath empty to use a default gray "clay" material.
- AGS Hidden to GI: All objects assigned with an Architectural Glass material hint (in "Translate Shaded") will not contribute to global illumination. e.g., these objects will not cast shadows. Note that this can be done on a per-object basis as well, by accessing the Maxwell Attributes for specific objects. (See Object Attributes)
Maxwell Features
For quicker faster test renderings, it is often useful to disable certain Maxwell features temporarily. These controls affect the exported MXS, not Fire (which has an independent set of controls.)
