What's new

1.5.3

Fixes

  • Fixed the analysis screen layout on small windows: the profile chart and chart tabs no longer overlap the footer buttons, and the overview panel reaches the bottom of the screen
  • Fixed a phantom selection band at the right edge of the region coordinate fields
  • Fixed the map border overlapping the seed row buttons
  • Fixed the spawn score ignoring nearby structures, mis-scaled slope scoring and a distorted water share when the preview layer is underground

Improvements

  • Noise maps (temperature, humidity, continentalness, erosion) now draw smooth gradients instead of color bands, aligned with real biome boundaries
  • The "Analysis" button moved to the sidebar, below the Seeds button
  • The world analysis screen was rebuilt in the seed search style: region coordinates now define the analyzed area, a stats panel with spawn score, a terrain cross-section, a height histogram, biome/terrain share tabs, map box-selection, structure distances, and CSV/JSON reports
  • The mouse wheel and the settings screen share one zoom ladder (16 down to 1 pixels per chunk); zooming applies instantly instead of rebuilding the map, and hitting a limit shows a hint
  • A scale bar with a zoom slider sits in the bottom-left of the map: click or drag it to change the zoom level
