# 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).
