Solution: To make more memory available for the rendering process, use one or more of the following
strategies:
Reduce the size of the image to be rendered. See
and
Render Performance and Image Size/Quality
Close unnecessary views in the Revit project.
Close unnecessary applications.
Not Enough Memory to Save to Project
Error: Not enough memory to save to project.
Issue: This message displays when you render an image and click Save to Project, but the computer has
insufficient memory to perform the operation.
Solution: If desired, export the image to a file. To increase available memory, close other Revit projects, or
exit Revit and restart it.
Rendering Process Is Taking Too Long
Symptom: The rendering process is taking too long, or is taking longer than expected.
Issue: Many factors can affect the amount of time required to render an image, including image size,
resolution, render quality settings, lighting, complex materials, and more.
Solution: See
render time. It also provides recommendations and tips on how to balance the need for a quality image with
the amount of time required to render it.
Rendered Image Is Black
Symptom: All or part of the rendered image is black.
Issues and Solutions: If parts of the rendered image are black, some image files used by render appearances
or decals may be missing. See
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.
