changedBeach Spawn System - Characters now spawn on beaches instead of mountain peaks - Configurable height range filters spawn locations to terrain between 100-3000cm above water level - Algorithm searches expanding rings to find the lowest valid terrain - Fallback system prefers lower elevations when no ideal beach is found

addedPCG HISM Tools (Editor/PIE only) - Added UMOHISMCullingSubsystem - World subsystem that periodically refreshes tagged PCG actors - Added MO Force HISM Tree Build PCG node - Forces HISM tree rebuilding after mesh spawning - Tag-based filtering allows selective refresh of specific PCG volumes (e.g., "FarTreesPCG")

changedImprovements

addedMOGameMode Configuration - New MaxSpawnHeightAboveWater property (default 3000cm) - defines beach ceiling - New MinSpawnHeightAboveWater property (default 100cm) - defines beach floor - Improved spawn search logging for debugging terrain detection - Voxel seed integration documented for procedural world generation

fixedFixed spawn algorithm preferring highest terrain instead of lowest - Fixed search loop exiting on first land hit instead of continuing to find beaches - Fixed fallback spawn using mountain peaks instead of lowest available terrain
