Why don't my URP volumes blend smoothly?

Volume Mode = Local with non-zero Blend Distance. Higher priority overrides lower; combine via Weight slider for cross-fade. Global volumes apply everywhere with priority 0 baseline.

What's Blend Distance?

Outer fade range. As player approaches volume bounds, weight ramps from 0 to 1 across that distance. Smooth visual transition.

Each Volume references a Volume Profile asset. Multiple volumes' overrides interpolate per-property based on weights. Override a single property in only the volume that should change it.

Fix: URP Volume Overrides Don't Blend

Quick answer: Volume Mode = Local. Blend Distance > 0 for fade-in. Per-property override in profile.

Two volumes overlap; vignette doesn't blend across boundary. Hard cut. Blend Distance was 0.

The Fix

VolumeA (Local):
  Priority:           1
  Blend Distance:     5
  Profile:            Outdoor (Vignette intensity 0.0)

VolumeB (Local):
  Priority:           2
  Blend Distance:     5
  Profile:            CaveTunnel (Vignette intensity 0.6)

Player crosses 5m fade region: vignette ramps 0 -> 0.6.

Blend Distance creates the smooth interpolation. Per-property overrides only affect what's checked.

Verifying

Walk through fade. Vignette ramps. Snap distance 0 = abrupt change.

“Blend Distance. Per-prop. Smooth fade.”
