Schaken-Mods 9092858a58 updated to the latest editor
I updated everything to the latest Unity Editor. Also realized I had the wrong shaders on my hairs, those are fixed and the hairs look MUCH better!

# Scene Depth Node
## Description
Provides access to the current **Camera**'s depth buffer using input **UV**, which is expected to be normalized screen coordinates.
Note: Depth buffer access requires depth buffer to be enabled on the active **Render Pipeline**. This process is different per **Render Pipeline**. It is recommended you read the documentation of your active **Render Pipeline** for information on enabling the depth buffer. If the depth buffer is unavailable this [Node](Node.md) will return mid grey.
Note: The executed HLSL code for this [Node](Node.md) is defined per **Render Pipeline**, and different **Render Pipelines** may produce different results. Custom **Render Pipelines** that wish to support this [Node](Node.md) will also need to explicitly define the behaviour for it. If undefined this [Node](Node.md) will return 1 (white).
NOTE: This [Node](Node.md) can only be used in the **Fragment** [Shader Stage](Shader-Stage.md) and it is not guaranteed to work with an opaque material.
#### Unity Render Pipelines Support
- High Definition Render Pipeline
- Universal Render Pipeline
## Ports
| Name | Direction | Type | Binding | Description |
|:------------ |:-------------|:-----|:---|:---|
| UV | Input | Vector 4 | Screen Position | Normalized screen coordinates |
| Out | Output | Float | None | Output value |
## Depth Sampling modes
| Name | Description |
|----------|------------------------------------|
| Linear01 | Linear depth value between 0 and 1 |
| Raw | Raw depth value |
| Eye | Depth converted to eye space units |
## Generated Code Example
The following example code represents one possible outcome of this node.
```
void Unity_SceneDepth_Raw_float(float4 UV, out float Out)
{
Out = SHADERGRAPH_SAMPLE_SCENE_DEPTH(UV);
}
```
