Transparency specifies the amount of light that strikes the surface at a 90-degree angle and bounces off.
Translucency specifies the amount of light that strikes the surface at a very shallow angle (close to 0 degrees)
and bounces off.
To determine the amount of light that bounces off the surface at any other angle, Revit Architecture
interpolates between these 2 values. The effects of these values can be altered by the value of the Glossiness
property.
Specifying a Render Appearance Color
To specify a color for a render appearance property, use the Render Appearance tab of the Materials dialog.
(See
Changing the Render Appearance of a Material
on page 465.) You can specify either a single color or an
image file that defines a custom color, design, or pattern.
■
Single color
: For the Color property, select Single Color. Click the color swatch. On the Color dialog,
select the color to use. (See
Colors
on page 514.) Click OK.
■
Image file
: For the Color property, select Image file. Specify the desired image file and its display properties.
See
Specifying an Image File for a Render Appearance
on page 476.
Specifying an Image File for a Render Appearance
To use a unique color, design, pattern, texture, or bump map for a render appearance, you can specify an
image file. You specify the file and its display properties (such as rotation and sample size) on the Render
Appearance tab of the Materials dialog. (See
Changing the Render Appearance of a Material
on page 465.)
NOTE
A complicated design or texture for a render appearance can increase the amount of time required to
render an image. See
Render Performance and Materials
on page 1174.
To specify an image file
1
For Image File, click
(Browse), navigate to the file, and open it.
Revit Architecture supports image files of the following types: BMP, JPG, JPEG, and PNG. See
Best Practice for Storing Image Files
on page 507.
2
For Sample Size, specify the size that the image represents.
For example, if the image represents 100 mm, enter
100
.
3
For Rotate, specify degrees of rotation in a clockwise direction.
You can enter a value between 0 and 360, or use the slider.
4
If you are specifying an image file to define a custom color, for Brightness, specify a value.
