In this quick Unity tutorial, I show you how I add a Vignette effect in Unity using URP, and how I control it at runtime. First, I create a Global Volume (Hierarchy > right click > Volume > Global Volume), then I make a new Volume Profile from the Inspector. Inside that profile, I add an override (Add Override > Post-processing > Vignette) so I can tweak the core settings right away. Once the Vignette is added, I walk through what each setting actually does: Intensity for how strong the effect is, Smoothness for softer or harder edges, Roundness for the shape, and Color for mood and style. You can use these to go from a subtle cinematic fade to a harsh border, or even a tinted look for more dramatic moments. The key “gotcha” is your camera: if post-processing isn’t enabled on the camera, you won’t see anything—so I make sure to tick that checkbox. After that, I jump into scripting so you can change the Vignette in real time. I grab the Volume component, try to pull the Vignette from the profile, warn if it’s missing, and then on Space key press I set intensity to 0.5f. That’s a simple pattern you can reuse for damage feedback, low-health indicators, or cinematic transitions.
