|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The HD Sample Buffer Node samples a buffer directly from the Camera.
|
||
|
|
|
||
|
|
## Render pipeline compatibility
|
||
|
|
|
||
|
|
| **Node** | **Universal Render Pipeline (URP)** | **High Definition Render Pipeline (HDRP)** |
|
||
|
|
| -------------------- | ----------------------------------- | ------------------------------------------ |
|
||
|
|
| **HD Sample Buffer** | No | Yes |
|
||
|
|
|
||
|
|

## Generated Code Example
|
||
|
|
|
||
|
|
The following example code represents one possible outcome of this node:
|
||
|
|
|
||
|
|
```c#
|
||
|
|
float4 Unity_HDRP_SampleBuffer_float(float2 uv, SamplerState samplerState)
|
||
|
|
|
||
|
|
{
|
||
|
|
|
||
|
|
return SAMPLE_TEXTURE2D_X_LOD(_CustomPostProcessInput, samplerState, uv * _RTHandlePostProcessScale.xy, 0);
|
||
|
|
|
||
|
|
}
|
||
|
|
```
