Rendered Image Is Washed Out Or Faded; Elements Are Gray In Rendered Image; Entourage Did Not Render Correctly - Autodesk 256B1-05A761-1301 - AutoCAD Revit Structure Suite 2010 User Manual

If the rendered image is all black, it could be caused by the following:
No lights: The render settings do not include natural or artificial light. For example, suppose you specify
an interior lighting scheme that uses artificial lights only, but all interior lights are turned off.
To correct this situation, in the Rendering dialog, check the lighting settings. Change them to include
natural light or artificial light, or both. See
needed, turn on artificial lights. See
Exposure settings: The exposure settings are not defined correctly.
To correct this situation, check the exposure settings. In the Rendering dialog, under Image, click Adjust
Exposure. See

Rendered Image Is Washed Out or Faded

Symptom: The rendered image shows too much light, so it looks washed out or faded.
Issues and Solutions: To solve the problem, try the following:
Exposure: Check the exposure setting. Try using a darker exposure. See
Rendered Image
Initial Intensity: The Initial Intensity settings for the light sources may be incorrect. In general, Luminous
Flux (lumens) provides more accurate lighting in a rendered image than Wattage. Determine the
manufacturer value for lumens, and enter this value for the Luminous Flux parameter of the Initial
Intensity dialog. (See
Wattage and Efficacy: If you specify a Wattage value on the Initial Intensity dialog, be sure to also specify
a value for Efficacy. (If you change Wattage alone, you may make the light source unintentionally bright.)
Efficacy is the amount of light (luminous flux, measured in lumens) produced by a light source as a ratio
of the amount of energy consumed to produce it (measured in watts).
Examples: For a 100 watt tungsten incandescent (110 V), efficacy is 175. For a 32-watt fluorescent tube
(T8), efficacy is 60.
After changing the Efficacy value, render the image again. Try adjusting the Efficacy value until you
achieve the desired result in the rendered image.

Elements Are Gray in Rendered Image

Symptom: In the rendered image, some of the elements display as gray. They do not display render
appearances as expected.
Issue: This problem occurs when you upgrade a Revit 2008 (or an earlier release) project that uses custom
materials. During the upgrade process, Revit Architecture upgrades all standard materials to use the new
render appearances. However, it cannot upgrade any custom materials.
Solution: Assign render appearances to the custom materials. See
Material on page 475.

Entourage Did Not Render Correctly

Symptom: The 3D view contains entourage (such as cars and people), but it did not render properly.
Issue: This problem occurs when the entourage objects do not have render appearances assigned to them.
Solution: Assign render appearances to the entourage objects. See
