Sample Cubemap Node

Description

Samples a Cubemap and returns a Vector 4 color value for use in the shader. Requires a Direction (Dir) input in world space 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.
