Shader Graph Extras
Released
Editor/UpgradedShaderGraph/Nodes/UniversalNodes/SceneRoughness.cs
An editor-only Shader Graph node for the Universal render pipeline that exposes a Scene Roughness output. It defines a hidden Vector2 input for texture coordinates and a float output that emits shader code calling Roughness::Sample with those coordinates.
