- Bump high to 30m chunk / HD<20m and ultra to HD<30m so HD models
persist further before swapping.
- Render the 5 graphics preset cards on a single row.
- Vegetation LOD selection now uses the distance to the nearest instance
in each chunk instead of the chunk centre, matching MapInstancingSystem
and avoiding premature LOD swaps when the camera enters a chunk.
Restore ultra to its original behaviour (50m chunk streaming, HD within
20m, no fog) and introduce a new max preset that disables chunk streaming
entirely (loads all chunks unconditionally) and pushes the HD/LOD swap
distance to 50m. Add chunkStreamingEnabled flag to GraphicsPresetConfig
so the streaming gate honours the preset. The settings card label shows
'All' when streaming is off.
