This tutorial covers lighting in Vray using an HDRI Sky only. The following steps will be shown: Creation of the Vray dome light and loading the HDR/EXR image file, reducing the HDRI gamma to introduce sharp defined shadows, overriding the environment background and reflection with a second unmodified HDRI, and finally generating a render with an alpha channel for use in post production.
Please note that the scene is lit with one of Peter Guthrie’s HDR images. 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! The principles shown in this tutorial are applicable should be perfectly suited to a variety of HDR imagery.

The above images were produced for a private developer client & friend of mine. The building site is not far from Clapham Junction (not far from where I currently work and in a part of London that I know reasonably well: I’m going to have to stop doing everything in 3D and start taking more photographs for these projects at some point I think!) I really enjoyed the fast turn around on this job. In addition it represented a culmination of a lot of learning on previous jobs. The job is ongoing as there are several phases to the actual building project. More images will follow from the project in time. I generated these images with all the typical tools: 3DS Max 2011, Vray, Photoshop and possibly one of my more valuable tools: Google Street View!

The above images represent my not so recent foray into zbrush, character rigging as well as some extensive Onyx Tree and trusted Peter Guthrie grass tutorials. The purpose of these images (apart from the obvious learning benefit to myself) was to produce a humorous yet slightly disturbing birthday card for a close friend. I’m pleased to say she was suitably amused and disturbed. All in all I used 3DSMax, vray, Onyx Tree, Zbrush, Photoshop, After Effects and Magic Bullet Photolooks (I think!) I have learned a tremendous amount about both zbrush and onyx tree and would love to produce a few tutorials soon the things I’ve found useful.
