DamageVignette - Visual Health Indicator

The DamageVignette mod adds a special edge-darkening effect to the screen that appears when your health is low. This works similarly to the world border approach effect, but with a red tint signaling danger.

When your health level drops to critical values, a red vignette appears on the screen, warning you of the urgent need to restore health. This is a simple but effective way to always be aware of your condition in combat.

If you have Cloth Config and Mod Menu mods installed, you can configure the health thresholds at which the effect appears, as well as its intensity. The mod is fully compatible with Iris Shaders.
