# Sample Texture 3D Node

## Description

Samples a **Texture 3D** 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.

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.

NOTE: This [Node](Node.md) can only be used in the **Fragment** [Shader Stage](Shader-Stage.md).

## Ports

| Name        | Direction           | Type  | Binding | Description |
|:------------ |:-------------|:-----|:---|:---|
| Texture | Input | Texture 3D  | None | Texture 3D to sample |
| UV      | Input | Vector 3    | None  | 3 dimnensional UV coordinates |
| Sampler | Input | Sampler State | Default sampler state | Sampler for the texture |
| RGBA  | Output    | Vector 4  | None  | Output value as RGBA |

## Generated Code Example

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

```
float4 _SampleTexture3D_Out = SAMPLE_TEXTURE3D(Texture, Sampler, UV);
