Lighting, GI and Probe Volumes

Inspect the installed pipeline/version, active quality asset, color space, tone mapping, lighting mode and target hardware. Define a reference camera and a repeatable exposure/look before compensating with more lights.

• Separate direct light, baked indirect light, probe-lit dynamic objects, reflections and post-processing when tracing a mismatch. Compare the same camera, time of day and exposure.
• Choose baked, mixed or real-time contributions according to motion and performance needs. Verify lightmap UVs, contributing renderers, scale and bake settings before increasing texture resolution.
• Check Adaptive Probe Volume support in the actual pipeline/renderer and quality settings. Configure the relevant baking set, scene participation, probe placement/density and renderer sampling using version-matched tools.
• Diagnose leaks through geometry thickness, probe validity/placement, bias and dilation before hiding them with a global intensity reduction. Check moving objects through doors and across scene boundaries.
• Place reflection probes for their spatial influence and verify box projection, blending and importance where supported. A reflection problem is not automatically a diffuse GI problem.
• Tune shadow distance/cascades and the actual screen-space need before raising atlas resolution. Profile extra lights, shadow casters, bandwidth and memory on the intended quality tiers.
• Preserve reproducible bake inputs and authored scene settings. Do not change all project lighting or quality assets to repair a single local material.

Verify indoor/outdoor transitions, static and moving objects, representative materials, camera distances and all supported quality tiers. Report bake/build evidence separately from visual approval.
