Scene Depth

Upscaled Scene Depth

The Sample Upscaled Scene Depth node works exactly like the SceneTextures:SceneDepth node found in stock UE5. It will sample the current screen position if not UVs are supplied or you can customize the UVs that you want to sample from.

The goal of this node, and the underlying accumulated SceneDepth is to approximate what TSR does for the SceneColor that you see, where it will use a few frames of history to reproduce a higher resolution version of the rendered image, than is actually rendered by the base pass. This also solves the jitter that you can see with more aggressive TSR upscales in effects that use the SceneDepth in later stage post process materials.
