V-Ray normal map

- [Man] One of the big pluses of working with the V-Ray engine is the ability it gives us to both create and render realistic materials. And of course, one common element in many such materials is the appearance of surface detail on an object. And for the longest time in render engines this has been accomplished by means of bump mapping a rendering trick that uses grayscale values in a mapping order to simulate the appearance of height and detail on a surface. White areas appearing raised up and black areas being pushed down or left on touched depending on how the application implements the feature. Now initially bump mapping, and the next evolution of that technology, the normal mapping that we will look at here may appear to do the same thing because normal maps are also a render time fake but whereas bump maps use grayscale values to provide up or down information to the renderer, a normal map uses red, green and blue…
