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 |
