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.

Ports

Name	Direction	Type	Binding	Description
Cube	Input	Cubemap	None	Cubemap to sample
View Dir	Input	Vector 3	View Direction (object space)	Mesh's view direction
Normal	Input	Vector 3	Normal (object space)	Mesh's normal vector
Sampler	Input	Sampler State	Default sampler state	Sampler for the Cubemap
LOD	Input	Float	None	Level of detail for sampling
Out	Output	Vector 4	None	Output value

Generated Code Example

The following example code represents one possible outcome of this node.

float4 _SampleCubemap_Out = SAMPLE_TEXTURECUBE_LOD(Cubemap, Sampler, reflect(-ViewDir, Normal), LOD);
