Maxwell emitters always cast shadows, so this option is disabled when editing a Maxwell light type.
Point
Point lights are converted into emitting spheres
formZ’s Point lights are supported by the plugin. Point lights have the following unique parameters:
...
Enabled: When enabled, the light will be exported to the Maxwell scene.
- Hide from camera: Enabling this option makes the lamp geometry invisible to the camera, but still allows it to contribute to the lighting calculation (it will cast shadows, refract etc).
- Hide from Reflections / Refractions: When enabled, the lamp geometry will not be reflected or refracted in other objects.
- Hide from Global Illumination: When enabled, the lamp geometry will be visible, but it will not cast shadows or reflect light back onto other objects.
- Quality: [1-Lowest - 5 Highest] Controls the number of faces (polygons) making up the emitter object. The default value (2) should work in almost all cases. Increasing this value may eliminate lighting artifacts, but will also increase render time.
- Diameter: Sets the diameter of the emitter sphere (bulb). Geodesic spheres are used for an even of distribution and maximum efficiency.
Cone (Spotlight)
Cone widget: Falloff region lies within the inner and outer circles
formZ’s Cone lights are supported by the plugin. Cone lights have the following unique parameters:
...
- Hide from camera: Enabling this option makes the lamp geometry invisible to the camera, but still allows it to contribute to the lighting calculation (it will cast shadows, refract etc).
- Hide from Reflections / Refractions: When enabled, the lamp geometry will not be reflected or refracted in other objects.
- Hide from Global Illumination: When enabled, the lamp geometry will be visible, but it will not cast shadows or reflect light back onto other objects.
- Width, Height: The width and height of the Softbox. The width is always level with the ground plane.

field extents
The Ambient Field t light was designed to flood architectural interiors with a soft, diffused light. This light type works by filling a cubic volume with a "cloud" of randomly oriented, light-emitting triangles.
The light's Origin and COI handles can be adjusted to define the minimum and maximum points of the world-aligned cubic volume. This light is not directional.
Parameters Tab
- Quality: (1-100%) Controls the number of light-emitting triangles created at render time. In most cases a setting of between 1 and 10 is sufficient. If light on neighboring surfaces looks uneven ("blotchy"), increase this parameter. Higher values require longer to render.
...
- Spin: Controls the rotation of the fixture about the axis defined by the light origin and COI. The origin of rotation (0 degrees) always points ‘down’ to the ground plane (XY plane).
- Length: Controls the length of the IES distribution pattern widget in the 3D modeling space.
Projector
Projector light
Projector lights can be used to simulate light beams, video projectors, and the like. Please see the Maxwell documentation about Spot emitters for more details on these parameters.
