Reflection

Reflection is the familiar physical phenomenon where an image of an object is cast back from a particular kind of surface, such as glass or water. Using the PositionToPoints node, you can replicate this effect in your render result of 3D objects, and using the Reflection node, you can adjust the controls for creating the reflection effect. PrmanRender uses raytracing to create this effect and you can use the Reflection node to adjust the result. Without the PrmanRender node and RenderMan Pro Server software though, the Reflection node has no effect.

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	Either: • The 2D image you’re using for the surface texture, or • Another shader node, such as Diffuse, Specular, or Emission. Adding several shader nodes one after the other allows you to produce more complex effects.
Output	unnamed	The 3D geometry object to which you want to apply a reflection effect. If you want to apply the same effect to several objects, you can also connect a MergeGeo node here.
