Quick answer: Unity reflection probe baked at 256x256 cooking to 64x64 on mobile? Probe importer downsamples based on quality settings - override per probe or raise the quality tier's reflection resolution.
Showcase probe shows crisp reflections in editor; mobile build shows blurry chunky reflections.
Override per probe
ReflectionProbe inspector > Override. Pick the resolution explicitly. Quality settings cap is overridden per asset.
Raise quality tier cap
Project Settings > Quality > Reflection Probes. Increase the cap for mid-tier mobile.
Bake at runtime for hero probes
For tutorial/cinematic moments, bake one probe at 1024x1024 at scene load. The cost is paid once; impact is significant.
“Quality settings cap reflection resolution by default. Per-asset overrides exist.”
Document per-platform reflection budgets. The blurriness is a quality bug; tracking budgets makes it a design decision.
