# Sampler State Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Defines a **Sampler State** for sampling textures. It should be used in conjunction with sampling [Nodes](Node.md) such as the [Sample Texture 2D Node](Sample-Texture-2D-Node.md). You can set a filter mode with the dropdown parameter **Filter** and a wrap mode with the dropdown parameter **Wrap**.
|
||
|
|
|
||
|
|
When using a separate **Sample State Node** you can sample a **Texture 2D** twice, with different sampler parameters, without defining the **Texture 2D** itself twice.
|
||
|
|
|
||
|
|
Not all filtering, wrap, and Anisotropic filtering modes are available on all platforms.
