- Forum Thread Discussion: https://discussions.unity.com/t/persistent-glitches-light-leaks-with-adaptive-probe-volumes/1705764
- Can’t use Debug Probe Sampling to find out why a vertex turns white. The tool works per-pixel, and if I switch APV to Per-pixel mode, the white pixels become stochastically scattered, making it impossible to pin one down for analysis.
