Render U V s Dialog 915
Inter face
Width/Height—The horizontal and vertical
dimensions of the output (rendered) template
image in pixels.
Guess Aspect R ati o—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 p ainting on the bitmap easier
because the bitmap is at the correct aspect ratio
for the mesh.
Wa rn in g : Using this function can result 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 viewer 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 fully 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, all faces will show the overlap
color, ignoring the fill color.
[color s watch]—Shows the fill color used for faces
when Mode is set to Solid. To change the color,
click the swatch.
Alpha—Sets the alpha-channel value for the fi ll
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 sa v 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 fil l is rendered. This se tting ignores
the Alpha value, and sets fill alpha to 0.0; that
is, fully transparent.
