Note: ThevaluesoftheImageAspectandWidth
and Height buttons can change, depending on
whichoutputformatyouselectfromthislist.
Aper ture Width (mm)—Lets you sp ecify an apertu re
width for the camera that creates the rendered
output.Changingthisvaluechangesthecamera’s
Lens value. This affects the relationship between
the Lens and the FOV values, but it doesn’t change
the cam era’s view of the scene.
For example, if you have a Lens setting of 43.0 mm,
and you change the Aperture Width from 36 to
50, when you close the Render Scene dialog (or
render), the camera Lens spinner has changed to
59.722, but the scene still looks the same in the
viewport and the rendering. If you use one of the
preset formats r ather than Custom, the aperture
width is determined by the format, and this control
is replaced by a text display.
Width a nd Hei ght—Let you set the resolution
oftheoutputimagebyspecifyingthewidth
and the height of the i mage, in pixels. With
Custom format, you can set these two spinners
independently. With any other format, the two
spinners are locked to the specified a spec t ratio,
so adjusting one alters the other. The maximum
w idth and height is 32,768 x 32,768 pixels.
Preset resolution buttons (320x240, 640x480, and so
on)—
Click one of these buttons to choose a preset
resolution. You can customize these buttons:
right-click a button to display the Configure Preset
dialog (page 3–33), which lets you change the
resolution specified by the button.
Image Aspect—Lets you set the asp ect r atio of the
image. Changing this value changes the Height
value to maintain the correct dimensions for the
active resolution. When you use a standard format
rather than Custom, you can’t change the aspect
ratio, and this control is replaced by a text display.
In 3ds Max, the Image Aspect value is always
expressed as a multiplier value. In written
descriptions of film and vide o, often aspect
ratio is also described as a ratio. For example,
1.33333 (the default Custom aspect ratio) is often
expressed as 4:3. This is the standard aspect ratio
for broadcast video (both NTSC (page 3–980)
and PA L (page 3–988)) when letterboxing is not
used. (Letterboxing shows the f ull width of a
w ide-screen film format, framed by black regions
above and below.)
When using a custom output size, the lock
button to the left of Image Aspect locks the aspect
