Material: Reflection Layer This section is about how to add and edit the refection layer. Please click on the red cup in the scene. Click on Edit button under Material selections in properties. Adding Reflection Layer 1. Click on the “+” next to Cup_red under Scene Materials to pull out all the layers. Right click on Reflection Layer. Select “Add new layer “to add a new reflection layer for this material. There will show Reflection under the material control section, as it shows on the right. 2. To remove a new added layer, right click on the layer you wish to remove then select remove. 3. By Default the reflection layer has a fresnel map which varies the amount of reflection based on the viewing angle. If that map is removed then the reflection is constant over the whole material. Since the reflection color is set to white this leads to complete reflection on the whole material. This is a good setting for chrome or a mirror, but not most materials. 4. Now we will go through the specifics of the fresnel map. Click on Reflection on the right section, and then click on the m box to set reflection. 26 V-Ray for Rhino
5. If it is not already enabled scroll down the box next to Type, and then select Fresnel. Fresnel IOR is to control the reflection intensity. Keep the default value of 1.55, then click Apply. 6. Click on the Material Preview again. The Material now has reflection quality with the same color on it. 6. Notice the “m” on the right side of the Reflection is now changed to “M”. That means the Map has some other characters associated with it now. Please use the same method and apply Fresnel to other colors and render it. The white spot on the cup is the Rectangular light from above 7. Below image rendered with Fresnel IOR set to 2.5, it has more reflection and looks more like a metal texture now. The cup has some black reflection due to the default setting of the background color is black.
