# Texture 3D Asset Node
## Description
Defines a constant **Texture 3D Asset** for use in the shader. To sample the **Texture 3D Asset** it should be used in conjunction with a [Sample Texture 3D Node](Sample-Texture-3D-Node.md). When using a separate **Texture 3D Asset Node**, you can sample a **Texture 3D** twice, with different parameters, without defining the **Texture 3D** itself twice.
