Adding reflections to materials

…Reflections are a vital part of many materials.…But how much reflection we need varies…widely, depending on the material we're using.…I'm going to add a subtle reflection to…my metals outside, my door handles and railing frames.…The big deal with reflections is that they're computationally intensive.…That our real time, raytraced reflection on the floor…for example, would bring many game engines to their knees.…And doing this on a mobile device is out of the question.…They simply don't have the power.…So, we'll use some creative fakery in here.…

Pre-calculated images that move around and change dynamically.…I'll scroll back in my scene and go select one of those railing elements.…I'll pick a corner one here and press F to focus in on it.…This object is three materials.…Dark wood, a metal screen, and a brushed bronze.…I'm going to add a subtle reflection in the brushed bronze.…First, I'll scroll down and change the shader over from a specular shader.…I'll drop down to my shaders and I'll choose under, Reflective, Specular.…
