Structural Decay

Explosions no longer leave surviving blocks untouched.
Structural Decay adds realistic structural degradation to Minecraft by making blocks damaged by explosions transform into weakened or broken variants instead of remaining pristine.

Turn every blast into a lasting scar on the world.

Features

Material-Based Blast Degradation

Blocks that survive explosions may degrade depending on their material:

Stone Bricks → Cracked Stone Bricks
Stone → Cobblestone
Sandstone → Sand
Concrete → Concrete Powder
And more...

Supports All Explosion Sources

Works with:

TNT
Creepers
Ghasts
End Crystals
Beds / Respawn Anchors
Wither Explosions
Most modded explosions

Vanilla-Friendly Design

Designed to feel like a natural extension of Minecraft:

Uses existing vanilla block variants whenever possible
Balanced degradation probabilities based on blast proximity
Maintains immersion without feeling overly punishing

Mod Compatibility

Includes tag-based compatibility support for modded blocks.

Other mods and datapacks can define custom degradation behavior through tags/configuration.

Why Use Structural Decay?
