Enable Hostile Mobs to Spawn During Daytime
Locating the Configuration File
The mod's configuration file controls whether mobs can spawn when the sun is up. Navigate to your Minecraft instance folder, then to config/, and find the Daylight Mobs Reborn configuration file (typically a .toml or .json file depending on your mod loader version).
Enabling Daytime Spawning
Open the configuration file in a text editor. Look for the setting related to daytime mob spawning—this is usually labeled something like allow_daytime_spawning or daytime_spawn_enabled. Change the value from false to true.
Save the file and restart your Minecraft world or server. Hostile mobs will now begin spawning during daylight hours, even in well-lit areas.
Testing Your Changes
After restarting, venture into open daylight areas. You should encounter zombies, skeletons, and other hostile mobs spawning naturally during the day. If mobs still don't appear, verify that the setting was saved correctly and that you edited the right configuration file for your mod loader.
