In this 1 hour video tutorial you will learn how to create some complex Vray materials and works with vray render elements. Also we will composite the final work with Photoshop. I have used a simple toy in this tutorial but I recommend you to watch it completely because I tried to show several techniques which can be use in other rendering such as Architechtural visualization. Below is the low-res version of the tutorial, if you like to download the hi-resolution file then register in the CGArena forum and download the zip version of the high-resolution file.
