How to use IES light in V-Ray for Revit
This video is created by Chaos Group that shows how to apply lights (IES lights) in V-ray for Revit.
IES light type is applied to load and render naturalistic light distribution profile files (IES files). The icon is available in the V-Ray main toolbar.
V-Ray for Revit is compatible with IES lights in the project. If the IES light files are untraceable in any of the search paths in v-ray, it applies a generic IES file that lusters light uniformly in all directions.
An IES file refers to a text file that defines the depth of a light source at points on a spherical grid. It offers more photorealistic lighting effects in rendered images as compared to other types of light distribution.
V-Ray for Revit facilitates to enable and disable light groups in the Revit. Light groups are obtained by selecting the Rendering Settings in the view properties of the view to be rendered, and clicking on the ‘Artificial Lights’ button. This button is activated if the lighting scheme is arranged to a mode with artificial lights allowed.
