HD Scene Depth Node

Description

The HD Scene Depth node uses a UV input to access the current Camera's depth buffer. Unity expects normalized screen coordinates for this value. You can also use this node to access the mipmaps in the depth buffer.

You can only use the HD Scene Depth node in the Fragment Shader Stage and with non-opaque materials.

Ports

Name	Direction	Type	Binding	Description
UV	Input	Vector 4	Screen Position	Sets the normalized screen coordinates to sample.
Lod	Input	float	None	Sets the mip level that the sampler uses to sample the depth buffer.
Output	Output	Vector 3	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

Notes

To use the HD Scene Depth node in a Custom Render Pipeline, you need to explicitly define its behavior, otherwise it returns white.
