Added SkyboxEnvironmentUpdater to the scene and switched Environment Reflections to Custom with the generated SkyboxReflection cubemap; unassigned the borrowed Supercyan forest LightingData asset (m_LightingDataAsset -> 0) and lowered ambient intensity to 0.75. Gold material metallic 1 -> 0.9 to soften the reflection look. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
