About Structure Generation Improver (SGI: Foundations!)
From ModrinthImproves world generation by dynamically conforming terrain around structures, creating natural slopes and seamless integration with the surrounding landscape.
Structure Generation Improver (SGI: Foundations!) enhances Minecraft world generation by dynamically adapting terrain around structures to create natural foundations and smooth environmental integration.
Instead of leaving floating buildings, exposed undersides, or abrupt vertical terrain cuts, SGI analyzes each structure during world generation and intelligently fills cavities, generates adaptive slopes, and reconstructs biome-consistent surface layers. The result is terrain that appears organically shaped around structures, preserving immersion and visual coherence.
Key Features:
• Dynamic foundation generation beneath structures • Adaptive slope blending based on height difference and distance • Perlin-based curvature variation to prevent repetitive shapes • Biome-aware surface reconstruction (grass, sand, terracotta, snow, etc.) • Intelligent cavity detection and vertical fill correction • Configurable per-structure shell settings • Advanced blacklist system supporting:

Namespace-wide exclusions (e.g., minecraft.*)
Global wildcard (*)
Structure tags (#namespace:tag)
SGI operates during world generation and does not modify existing worlds retroactively. It is designed to be lightweight, deterministic, and compatible with modded structures.
Ideal for modpacks seeking more immersive terrain integration without redesigning structure packs or manually editing templates.
