Sample Texture 2D Array Node

Description

Samples a Texture 2D Array and returns a Vector 4 color value for use in the shader. You can override the UV coordinates using the UV input and define a custom Sampler State using the Sampler input. Use the Index input to specify which index of the array to sample.

NOTE: This Node can only be used in the Fragment shader stage.

Ports

Name	Direction	Type	Binding	Description
Texture Array	Input	Texture 2D Array	None	Texture 2D Array to sample
Index	Input	Vector 1	None	Index of array to sample
UV	Input	Vector 2	UV	Mesh's normal vector
Sampler	Input	Sampler State	Default sampler state	Sampler for the texture
RGBA	Output	Vector 4	None	Output value as RGBA
R	Output	Vector 1	None	red (x) component of RGBA output
G	Output	Vector 1	None	green (y) component of RGBA output
B	Output	Vector 1	None	blue (z) component of RGBA output
A	Output	Vector 1	None	alpha (w) component of RGBA output
