# Adaptive Probe Volumes (APV) in URP

> Approaches and resources for using Adaptive Probe Volumes to provide higher quality, more accurate lighting.

Adaptive Probe Volumes make [Light Probes](https://docs.unity3d.com/Manual/LightProbes.html) easier to use by automating placement. They also provide higher quality, more accurate lighting, because they light per-pixel not per-object.
