Camera Tab
Maxwell Render renders the active formZ view. To construct a Maxwell camera, the plugin obtains the eye point, center of interest, and focal length from the the formZ View Parameters (double-click on a view in the views palette). The resolution and pixel aspect ratio are obtained from the Camera View settings in View Parameters if these are in use; if not, the values specified in Display > Image Options... are used instead.
The Maxwell simulates a number of additional properties of physical cameras, and as such requires several parameters not found in formZ. These are specified though the Camera Tab. The options here will apply to all views/cameras rendered within the associated window. Maxwell Render options are also stored on a per-scene basis, so if you need a different set of camera parameters, create a new formZ Scene in the Scenes palette.

Maxwell 3 fully supports 3-Point Perspective, Orthographic, and Axonometric view types. However, the plugin must approximate formZ "2D Perspective" views with Maxwell's Shift Lens. Due to inherent differences between "2D Perspective" and "Shift Lens," this does not provide an identical match, but rather a starting point for cropping, which can be readily refined in Fire. |

Exposure
- EV Lock: When enabled, the current exposure is maintained when adjusting the f-stop, shutter speed, or ISO. If the f-stop is adjusted, the shutter speed value will be adjusted to compensate, and vice versa. If the ISO is adjusted, the shutter speed will compensate.
f-Stop: Specifies the diameter of the lens opening, or aperture, as an f-Stop value. Clicking on the triangle to the right exposes a menu of traditional f-Stop values in third-stop increments. Arbitrary values can be typed into the text field. Aperture size also affects not only image exposure, but Depth of Field (DOF). See Camera.
- Shutter: Specifies shutter speed, indicated as a fraction of a second. Clicking on the triangle to the right exposes a menu of traditional shutter speed values in third-stop increments. Arbitrary values can be typed into the text field. This parameter may be adjusted interactively in Maxwell while rendering.
...
- Type: Select Standard, Pinhole, Fisheye, Spherical, or Cylindrical lens. See Camera Lenses.
- Shift Lens: Adjusting the y-shift (rise) is useful in architectural rendering to eliminate converging parallels in tall buildings, approximating a two-point perspective. See Shift Lens.
- Approximate '2D Perspective' Views. When enabled, formZ "2D Perspective" views will be approximated using Maxwell's Shift Lens. Due to inherent differences between "2D Perspective" and "Shift Lens," this does not provide an identical match, but rather a starting point for cropping, which can be readily refined in Fire.
- Horizontal: Specifies the horizontal shift of the film plane relative to the lens, as a signed percentage (-100% to 100%).
Vertical: Specifies the vertical shift of the film plane relative to the lens, as a signed percentage (-100% to 100%).
Simulens...: Click to create realistic lens diffraction effects (glare). See SimuLens.
Note In most cases, you will NOT want to select the checkbox next to the three Simulens settings described above. Doing so adds unnecessary processing time to each sampling level update, and increases RAM usage during rendering. Instead, wait until the render has reached an acceptable SL for viewing the Simulens effect, stop the render, apply a Simulens effect to give you an idea of its influence, then disable Simulens again and resume the render. For adding Simulens effects to a range of MXI files after the render is completed, use File>MXI Batch Processing.
