Frequently Asked Questions

What key toggles the spawn overlay by default?

Press the F7 key to toggle the hostile spawn overlay on and off during survival exploration.

What is the difference between Always Spawning Color and Night Spawning Color?

"Always Spawning Color" highlights blocks that are dark enough for monsters to spawn day or night, while "Night Spawning Color" marks blocks safe during daytime that become hazardous after sunset.

Can you disable the overlay in naturally safe biomes?

Yes, enable "Ignore Peaceful Biomes" to suppress spawn warnings when operating inside mushroom fields or protected zones.
