Configuration

Every setting in the mod config file, with what it changes.

OptionWhat it does
hivemind_alert_radiusAlert broadcast radiusHow far (in blocks) a sighting alert reaches. Only monsters within this radius will converge on the player. Lower values = less swarming. Server-side setting.
hivemind_cooldownAlert cooldown (minutes)Minutes after an alert ends before a new one can trigger for the same player. Prevents back-to-back swarms. Server-side setting.
demobat_spawn_chanceDemo Bat spawn chanceProbability (0.0-1.0) that a Demo Bat natural spawn attempt succeeds in the Upside Down. Lower values mean fewer Demo Bats. Server-side setting.
demodog_spawn_chanceDemodog spawn chanceProbability (0.0-1.0) that a Demodog natural spawn attempt succeeds in the Upside Down. Lower values mean fewer Demodogs. Server-side setting.
demogorgon_spawn_chanceDemogorgon spawn chanceProbability (0.0-1.0) that a Demogorgon natural spawn attempt succeeds in the Upside Down. Lower values mean fewer Demogorgons. Server-side setting.
vecna_first_curse_delayFirst curse delay (minutes)How many real minutes after a player is first tracked before Vecna can attempt the first curse. Default: 15 minutes. Server-side setting.
hivemind_first_wave_delayFirst wave delay (seconds)How many seconds after a player is spotted before the first reinforcement wave arrives. Higher values give more time to fight or flee. Server-side setting.
upside_down_waterGenerate water in the Upside DownWhen enabled, water generates normally in the Upside Down dimension. Only affects newly generated chunks.
monster_numbersHivemind monster numbers overlayShows numbered labels above Upside Down monsters for debugging the hivemind AI system. Server-side setting; requires admin permissions in multiplayer.
hivemind_enabledHivemind reinforcementsWhen enabled, Upside Down monsters will call for Demodog reinforcements when they spot a player. Disabling this makes encounters isolated. Server-side setting.
hivemind_max_mobsMax hivemind mobs nearbyMaximum number of hivemind-aware monsters allowed near a player before reinforcement spawning stops. Lower values = less swarming. Server-side setting.
hivemind_max_wavesMax reinforcement wavesHow many waves of Demodog reinforcements can spawn per alert. Set to 0 to disable reinforcement spawning entirely while keeping alert broadcasting. Server-side setting.
rift_max_rendered_per_frameMax rifts rendered per frameMaximum number of rift portals that get full see-through rendering each frame. Extra rifts beyond this limit show the fallback swirl effect instead. Lower values improve FPS with many nearby rifts. Default: 3. Client-side setting.
tunnel_max_demodogsMax tunnel demodogsMaximum number of Demodogs that can patrol tunnels at once. Set to 0 to disable tunnel spawning. Server-side setting.
max_simultaneous_riftsMaximum simultaneous riftsMaximum number of rifts that can exist at the same time. When a new rift opens, the oldest rift will automatically close if this limit is exceeded. Default: 1. Server-side setting.
particle_multiplierParticle multiplierScales the number of particles for Mind Flayer and other heavy effects. Lower values improve performance. Set to 0 to disable particles entirely. Client-side setting.
possession_durationPossession duration (seconds)How many seconds a player can possess an Upside Down monster using Will's powers. Server-side setting.
rift_random_enabledRandom rift spawningWhen enabled, rifts will randomly spawn near players in the overworld after the world is awakened. Server-side setting.
vecna_repeat_cooldownRepeat curse cooldown (minutes)Minimum real minutes between repeated curses on the same player. Default: 120 minutes (2 hours). Server-side setting.
rift_durationRift duration (minutes)How long in real minutes a rift stays open before automatically closing. Range: 1-30 minutes. Default: 3 minutes. Server-side setting.
rift_max_intervalRift maximum interval (minutes)Maximum time in real minutes before a rift is very likely to spawn. The spawn chance ramps up between min and max. Server-side setting.
rift_min_intervalRift minimum interval (minutes)Minimum time in real minutes between random rift spawns per player. Lower values mean rifts can appear more frequently. Server-side setting.
rift_portal_render_depthRift portal render depthControls how many levels deep rift portals render. 1 = disabled (rifts show the End portal texture fallback), 2 = see-through with no recursion (best performance), 3+ = allow recursive rendering through multiple rifts (higher values cost more FPS). Default: 2.
rift_render_distanceRift render distance (blocks)How far away (in blocks) rift portals will render their see-through content. Rifts beyond this distance show the fallback swirl effect. Lower values improve performance. Default: 48. Client-side setting.

Frequently asked questions

How do I start The Awakening?
Find a sensory deprivation tank in your world and attack the creature trapped inside it. This triggers The Awakening and begins spawning dark dimension monsters and rifts in your world.
What happens after I trigger The Awakening?
Dangerous creatures like Demogorgons, Demodogs, and Demobats begin spawning through rifts that tear open randomly near your base. Torches and lanterns will flicker as a warning when dark forces approach.
How do I use telekinesis to fight?
Focus your telekinesis power on a mob by looking at it and holding the ability key. You can lift enemies into the air and throw them by moving your mouse, or activate Power Mode for increased knockback damage.
How do I open and close rifts?
Focus your rift manipulation power on any wall or floor surface for three seconds to tear open a portal, or use the same ability on an existing rift to seal it closed.
What should I do when Vecna curses me?
Keep a Walkman and Running Up That Hill music disc in your inventory—when nightmare visions start, the music will help break you free from the curse before it deals fatal damage.
Why am I taking health damage when I use psychic powers?
Using telekinesis and rift manipulation drains your hunger bar first. If you run out of food, the abilities will damage your health instead, so always carry enough food or candy bars.
How do I deal with Demodog packs?
Demodogs grow much stronger when grouped together, so use your flamethrower or telekinesis to separate and eliminate them quickly before they can coordinate attacks.
Can I change how often rifts spawn or how strong monsters are?
Yes—use the command `/strangerthingsconfig` to open the settings screen where you can adjust curse timers, rift spawn rates, and monster behavior to your preference.
What's the best way to defend my base from rifts?
Keep torches and lanterns lit around your base to get early warnings when they flicker, and use your rift manipulation ability to seal portals as soon as they appear before monsters pour through.
Should I keep the Walkman on me at all times?
Yes—Vecna's curse can trigger unexpectedly once The Awakening is active, and having the Walkman and a music disc in your inventory is your only reliable escape from deadly nightmare visions.
