What's Changed For Rendering - Autodesk 256B1-05A761-1301 - AutoCAD Revit Structure Suite 2010 User Manual

However, in Revit Architecture 2009, you have more control over the quality settings for rendered images.
For example, you can generate a quick draft quality image to check material settings, or use a higher quality
setting to generate a presentation-quality image. Higher quality rendered images require more time to
generate than lower quality images. Other characteristics of the building model can also increase rendering
time. Regardless of the quality setting you choose, however, the resulting rendering will be more accurate
and more detailed than the corresponding AccuRender image.

In Revit 2009...
Revit Architecture 2009 now performs similar
functions automatically when it renders an image.
You no longer need to perform these functions
as separate steps.
When you define render settings, you specify
whether the sky is cloudy or hazy (or both), or a
solid color. For the sun position, you can select
from predefined settings, or define a sun position
based on date/time/location or azimuth/altitude.
For rendered images, daylighting is performed
automatically. For advanced lighting quality in
interior views, you can enable daylight portals, if
needed.
You define render settings for each 3D view. To
apply defined render settings to other views,
create a view template. Then apply it to the de-
sired views.
Revit Architecture 2009 now performs these
functions automatically when it renders an image.
You no longer need to specify these settings.
Material definitions are stored as part of the pro-
ject file. Render appearances are stored in a local,
read-only library. If you change attributes for
render appearances, many changes are stored as
part of the project. If you specify image files for
render appearances, store the image files in a
directory, and point Revit Architecture to that
directory. To share custom render appearances
with team members, use File menu
Project Standards, and send them the directory
containing the image files.
