V-Ray Normal Map
- [Narrator] One of the big pluses of working with the V-Ray engine is the ability it gives us to both create and render ultra-realistic materials, and of course one common element in many such materials is the appearance of surface detail on objects. Now for the longest time in renders this was accomplished by means of bump mapping, a rendering trick the appearance of height or detail on a surface, white areas appearing raised up and black areas being pushed down, all left untouched depending on how the application is designed to work. Now initially, bump mapping, on the next evolution of that technology, normal mapping, so what we will be looking at here may appear to do the same thing. As again normal maps are a render time fake. But where is bump maps use gray-scale values a normal map uses R G and B data that corresponds directly with the X, Y and Zed, or Z, axes of 3-D space, information that tells the 3-D application which direction the surface normals are suppose to be…
