Camera Tab
Maxwell Render renders the active form•Z view. To construct a Maxwell camera, the plugin obtains the eye point, center of interest, and focal length from the the form•Z 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.

Maxwell 3 fully supports 3-Point Perspective, Orthographic, and Axonometric view types. (Views similar to form•Z's 2-Point Perspective may be created using the plugin’s Shift Lens feature. form•Z’s 2-Point Perspective does not model a shift lens-type camera, and so cannot be directly translated.)The plugin approximates 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.
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.
- 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%).
Info Shift lens does not tilt or swing the film plane.
