Frequently asked questions

How do I detonate a nuke block?
Place a Nuke Block on the ground, then send a redstone signal to it (using redstone dust, a lever, or a button). The block will power up and trigger a countdown before detonating.
What's the difference between placing a nuke block and using the spawner?
A Nuke Block requires redstone power and gives a standard 1 kt blast. The Nuke Spawner lets you hold different ore blocks or ingots in your offhand to control the blast size (from 0.01 kt to 200 kt) and detonate instantly where you're looking.
How do I drop a bomb from the sky?
Use the command `/spawnnuke falling x z yield` to drop a bomb at those coordinates with your chosen yield, or use the Nuke Spawner's falling bomb feature if available in your mod version. The bomb will animate falling before exploding on impact.
What happens to the landscape after a nuclear blast?
The explosion creates a giant crater with raised edges and transforms the surrounding area into a nuclear wasteland biome. Grass becomes coarse dirt, wood turns to basalt, and the terrain is left charred and barren.
Can I see the mushroom cloud from far away?
Yes, if you have the Distant Horizons mod installed, you can see the bright glowing mushroom clouds from very far distances, making large blasts visible across the entire map.
Do falling bombs work with flying ships or machines?
Yes, falling bombs are compatible with Valkyrien Skies ships and will drop naturally from moving flying machines, allowing you to create aerial bombardments.
How do I change the explosion graphics?
Open the in-game mod menu and access the client config to adjust visual settings like particle brightness, glow intensity, and mushroom cloud appearance.
What's the biggest blast I can create?
A Netherite Block in the Nuke Spawner creates a 200 kt explosion, which is the largest yield available in the mod.
Can I use commands to spawn nukes at exact coordinates?
Yes, use `/spawnnuke direct x y z yield` to instantly create a blast at specific coordinates, or `/spawnnuke falling x z yield` to drop a bomb from above.
Will this mod cause lag or performance issues?
Large explosions with many particle effects and terrain changes can impact performance depending on your hardware; consider using smaller yields or adjusting visual settings in the mod config if you experience lag.
