Iray+ is equipped with a range lighting types and options for each use case; simply add the values for your lights into the system and they will interact correctly with the chosen phscailly based materials, producing true photorealistic visualisations, no matter what the configuration is.
Iray+ allows you to incorporate any of the following lightning techniques:
Iray+ provides ready to use materials through its MDL and the lighting to match. Starting with the Physically correct Sky, a range of pre-calibrated HDR images are supplied for exterior, interior and studio-based environments. In addition, Iray has a range of material emissions and example goniometric lights preset to render - providing the foundations to be able to create custom profiles alongside these.
Iray+ has a flexible approach to lighting arrangements and structures, giving users the chance to interact with myriad lighting options within their scene. Iray+ favours light, meaning the more lighting there is in a scene, the faster an image will converge. Feedback on lighting behaviour is enhanced through the accuracy of external and internal light emitting objects, and with light path expressions users have ultimate flexibility over potential lighting structures.
