Sample Cubemap Node

Description

Samples a Cubemap and returns a Vector 4 color value for use in the shader. Requires View Direction and Normal inputs to sample the Cubemap. You can achieve a blurring effect by sampling at a different Level of Detail using the LOD input. You can also define a custom Sampler State using the Sampler input.

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);
