This tutorial covers updated techniques for lighting in Vray using an HDRI Sky and Vray Sun.
Please note that I have learned much of what is presented in this tutorial by going though Peter Guthrie’s blog in detail. In addition there are some other steps which I have worked out while experimenting with the technique. I felt it would be useful to try to consolidate what I have learned into one concise video. In addition, please note that the scene is lit with one of Guthrie’s HDR images which he sells online. The settings I have used in the tutorial suit his HDRIs well but the results may vary a little with other HDRIs. Don’t be afraid to adjust the setting and experiment! It would be nice to hear what kind of results other people get with different HDRIs. I would encourage you to check out Peter Guthrie’s blog, for a lot of detail on this topic (as well as many other areas of architectural visualisation.) The webpages of Ronen Bekerman and Bertrand Benoit also provide some very useful information on the topic of lighting with HDRI.
The following steps will be shown: Creation of the vray dome light, loading the HDR/EXR image file, creation and aligning of the vray sun to the HDRI, linking of the vray sun to the dome light, the parameter wiring of the dome light to control the rotation of the HDRI and finally generating a render with an alpha channel for use in post production.
