Surface detail can look flat when a scene's lighting gives little sense of recesses and raised edges. Screen Space Cavity & Curvature is a fullscreen and camera effect in the VFX and Shaders category that targets exactly that, working on the rendered image rather than on each material.
Cavity and curvature describe how a surface dips inward or rises outward, and an effect built around them adds definition to models after they are drawn. It supports the Built-in Render Pipeline, URP and HDRP, so the same effect can follow a project across pipelines. Among unity VFX options, a screen-space effect like this suits teams who want more visual depth without editing every asset in the scene.
