Render UVs Dialog 897
Inter face
Width/Height—The horizontal and vertical
dimensions of the output (rendered) template
image in pixels.
Guess A spect R a tio—Adjusts the Height value to
produce an output aspect ratio based on the Width
valueandthedimensionsoftheUVgrid.
For instance, if a rectangular UV grid measures
20 x 100 units and you click Guess Aspect Ratio,
it would try to keep the bitmap at the 1:5 aspect
ratio. This makes painting on the bitmap easier
because the bitmap is at the correct aspect ratio
for the mesh.
Wa rni ng: Using this function can res ult in Height value
that is not a power of 2. If your mesh is destined for a
real-time renderer, adjust the resulting Height value to
the nearest power of 2 after using Guess Aspect Ratio.
For example, if it sets Height to 650, change it to 512
before rendering the template.
Force 2-Sid ed —
When on, all UV edges are
rendered into the template. When off, only UV
edges of faces facing the v iewer are included; edges
of back-facing faces are not rendered.
Fill group
Fill is the coloring applied to the rendered bitmap
in the face areas between edges. By default, there’s
no fill; the bitmap color is black, and the alpha
channel is f ully transparent. You can change this
to a solid color or to shading derived from the
mesh and lighting in the scene, or from the normal
directions.
Note: The overlap color overrides the fill color . For
example, if Show Overlap is on and all visible faces
overlap other faces, a l l faces will show the overlap
color, ignoring the fill color.
[color swatch]—Shows the fill color used for faces
when Mode is set to Solid. To change the color,
click the swatch.
Alpha—Sets the a lpha-channel value for the fill
areas when Mode=Solid, Normal, or Shaded.
When Mode=None, the fill alpha is always 0.0
(transparent). Range=0.0 (transparent) to 1.0
(opaque). Default=1.0.
The alpha channel is included with the rendered
image only when you sav e in a format that supports
transparency, such as TIF or Targa.
Mode—Specifies the method used for filling faces
in the rendered template.
• None: No fill is rendered. This setting ignores
the Alpha value, and sets fill alpha to 0.0; that
is, f ully transparent.
