Simulate one explosion and export the damaged SchemLearn more

Estimate damage from a single explosion in a Minecraft Java schematic. Set power and center, account for block resistance and water, and simulate 1352 rays. Export affected coordinates and the resulting Schem.

How to use the result

  1. Step 1

    Upload a Java schematic, specify the center within its bounds, and set the explosion force. Download the report and the separate Schem with damaged blocks, then verify the result in a world copy.

What to know

  • Upload a Java schematic, specify the center within its bounds, and set the explosion force. Download the report and the separate Schem with damaged blocks, then verify the result in a world copy.
  • Uses Java 26.3 block blast resistances and the ServerExplosion ray algorithm: 1352 directions, attenuation, and water resistance for waterlogged blocks.
  • The tool's seed does not reproduce the world's random state. Entity damage, item drops, fire, and TNT chain reactions are not simulated. Entities in the original schematic are not copied.

Frequently asked questions

How to assess chunk damage from TNT explosion?

Estimate damage from a single explosion in a Minecraft Java schematic. Set power and center, account for block resistance and water, and simulate 1352 rays. Export affected coordinates and the resulting Schem.

How to start an explosion model inside your schema?

Upload a Java schematic, specify the center within its bounds, and set the explosion force. Download the report and the separate Schem with damaged blocks, then verify the result in a world copy.

Does the explosion model's seed match the world's random state?

The tool's seed does not reproduce the world's random state. Entity damage, item drops, fire, and TNT chain reactions are not simulated. Entities in the original schematic are not copied.
