Volumetric Lights 2 (URP) · Common Tasks

Transparency Support

Volumetric Lights relies on the depth buffer to determine object positions. Since transparent objects do not write to the depth buffer, they can be overdrawn by the volumetric effect. There are two solutions.

Option A — Adjust Render Queues

Set the volumetric light’s Render Queue to a value lower than your transparent objects (transparent queue starts at 3000). This ensures the volumetric effect renders before transparent objects regardless of scene position.

Note: If you are using the Volumetric Lights Render Feature (composition blur), changing the render queue in the volumetric light inspector has no effect. Instead, change the Render Event in the Render Feature inspector.

Option B — Depth Pre-Pass Render Feature

Add the Volumetric Light Depth Pre-Pass Render Feature to your URP Renderer for more precise control.
