Adaptive Light Probe Volume- Too many probes

Despite my level being entirely contained within my Adaptive Probe Volume size, there are a lot of probes being created way outside of my level. How can I remove these probes so I’m not wasting memory and/or disk space?

You can lower the Max Probe Spacing in the lighting window (window > rendering > lighting). That’s about it. The structure of APV is such that having some probes outside the scene bounds is to be expected - it’s a global structure similar to an octree, where you directly control the size of the leaf nodes.
