# Load Texture3D
|
|||
|
|
|
|||
|
|
Menu Path : **Operator > Sampling > Load Texture3D**
|
|||
|
|
|
|||
|
|
The **Load Texture3D** Operator allows you to read a Texture3D’s texel value for specified coordinates and mip level. The float4 texel value is returned without any filtering.
|
|||
|
|
|
|||
|
|
This translates to a Load() call on the texture in High-Level Shading Language (HLSL). For information on the differences between loading and sampling, see [Loading and sampling](#loading-and-sampling).

## Operator properties
|

|
|

|
|
| **Input** | **Type** | **Description** |
|
|||
|
|
| ------------- | --------- | ------------------------------------------------------------ |
|
|||
|
|
| **Texture** | Texture3D | The Texture to read from. |
|
|||
|
|
| **X** | uint | The X coordinate of the texel to read. This is in the range of 0 to the width of the texture minus 1. |
|
|||
|
|
| **Y** | uint | The Y coordinate of the texel to read. This is in the range of 0 to the height of the texture minus 1. |
|
|||
|
|
| **Z** | uint | The Z coordinate of the texel to read. This is in the range of 0 to the depth of the texture minus 1. |
|
|||
|
|
| **Mip Level** | uint | The mip level to read from. |

## Limitations
|
|||
|
|
|
|||
|
|
This is a GPU only Operator and therefore does not work when plugged into **Spawn Context** ports.
