Sample Reflected Cubemap Node
Description
Samples a Cubemap with reflected vector and returns a Vector 4 color value for use in the shader. Requires View Direction (View Dir) and Normal inputs to sample the Cubemap. You can achieve a blurring effect by using the LOD input to sample at a different Level of Detail. You can also use the Sampler input to define a custom Sampler State.
If you experience texture sampling errors while using this node in a graph which includes Custom Function Nodes or Sub Graphs, you can resolve them by upgrading to version 10.3 or later.
