Lighting Enhancements

Lighting fixtures are now photometric and can be described by IES files. (Many manufacturers provide IES
files for their lighting fixtures, which you can download from their Web sites.) When you render an image,
Revit Architecture uses information in the IES file to determine the intensity of light at various points in
space. If you do not use an IES file to describe the light source, you can specify real-world lighting variables
based on manufacturer information. These improvements provide more accurate, realistic lighting in the
rendered image. See
During the rendering process, daylighting is performed automatically. For advanced lighting quality in
interior views, you can enable daylight portals, if needed. See
