T.W.O. – TRUE WILDLIFE OVERHAUL v1.2.0
Realistic wildlife: reduced density, different species during certain times, and smarter spawn management.
Required:
ScriptHookRDR2 V2
What this mod actually does
This mod changes how much wildlife spawns, when specific species are allowed to exist, and how animals react to danger.
It is not a graphics mod.
It does not replace textures.
It does not touch birds.
It does not touch Legendary animals.
It uses a mix of LML tuning file edits and .NET scripts, because doing only one of the two was not enough.
The LML side handles the ecosystem and schedules:
– wildlifemanager.ymt reduces overall wildlife density
– animalunalertedbehaviours.meta gives different species their own active hours
The script side handles enforcement and behavior:
– WildlifeSenses.dll makes animals harder to hunt by improving senses and panic/flee behavior
– WildlifeScheduleEnforcer.dll removes species outside their allowed time windows so they do not keep showing up at the wrong hours
The whole point is simple:
you should not be able to ride around at random hours and find everything everywhere.
Why this mod uses both files and scripts
At first I only reduced density, but animals could still appear too often.
Then I added schedules, but the game could still leave animals alive outside the hours they were supposed to be active.
That is why this mod now uses both tuning edits and enforcement.
wildlifemanager.ymt reduces wildlife globally.
animalunalertedbehaviours.meta changes what animals do and when they are supposed to be active.
WildlifeScheduleEnforcer makes sure specific species do not keep hanging around outside their real hunting windows.
So this is not just “less animals”.
It is:
– less wildlife overall
– species active at different times
– specific models suppressed and cleaned outside their allowed hours
What WildlifeScheduleEnforcer does
This is the part that stops the game from feeling random.
It tracks specific A_C_ animal models and checks the in-game hour.
When a species is outside its allowed time window, the script prevents that model from being available around the player and cleans up animals that should not still be there.
That means the mod is not just changing animations or idle behavior.
It is actively trying to stop the wrong animals from being present at the wrong times.
This was added because just editing behavior files was not enough.
For example, deer could still show up late at night even after changing their schedule, because the engine could leave them alive or spawn them in ways that were not fully controlled by behavior edits alone.
Species schedules currently used
Below are the actual species groups and time windows used by the mod, I will add more and more species each update.
DeerStrictCrepuscular
a_c_deer_01
a_c_buck_01
Active window:
05:00-08:00 and 18:00-21:00
These are the strictest herbivores in the mod.
Outside those hours they are meant to be gone.
This is one of the main goals of the overhaul but difficult to reach since you can still see some of them hanging around at the wrong hours… that’s because the game spawns so many of them.
CrepuscularHerd
a_c_elk_01
Active: 05:00-10:00 and 16:00-22:00
a_c_moose_01
Active: 05:00-10:00 and 17:00-22:00
a_c_bighornram_01
Active: 06:00-11:00 and 15:00-19:00
a_c_pronghorn_01
Active: 06:00-11:00 and 15:00-19:00
a_c_boar_01
Active: 19:00-05:00
a_c_javelina_01
Active: 18:00-06:00
This group is still time-dependent, but less strict than deer.
Elk and moose have wider dawn/dusk windows.
Boar and javelina are pushed much more into evening and night.
DiurnalGrazer
a_c_buffalo_01
a_c_buffalo_tatanka_01
Active: 06:00-11:00 and 15:00-19:00
These are daytime grazers with a quieter middle of the day and no reason to be active all night.
PredatorPack
a_c_wolf
a_c_wolf_medium
a_c_wolf_small
Active: 19:00-09:00
a_c_coyote_01
Active: 18:00-07:00
Pack predators stay much more tied to darkness, night and early morning.
PredatorSolo
a_c_cougar_01
a_c_panther_01
Active: 20:00-06:00
a_c_bear_01
a_c_bearblack_01
Active: 05:00-09:00 and 17:00-22:00
Cougars and panthers are mostly night predators.
Bears are set more around dawn and dusk.
NocturnalSmall
a_c_raccoon_01
a_c_possum_01
a_c_skunk_01
a_c_rat_01
a_c_bat_01
Active: 20:00-05:00
a_c_badger_01
Active: 20:00-04:00
These are intended to be night sightings.
DiurnalSmall
a_c_chipmunk_01
a_c_squirrel_01
Active: 07:00-18:00
a_c_rabbit_01
Active: 05:00-10:00 and 16:00-21:00
a_c_armadillo_01

a_c_gilamonster_01
a_c_iguana_01
a_c_iguanadesert_01
Active: 09:00-17:00
Not all small animals are treated the same.
Some are proper daytime animals, some are crepuscular, some are night-active.
SemiAquatic
a_c_alligator_01
a_c_alligator_02
a_c_alligator_03
Active: 18:00-08:00
a_c_beaver_01

Swamp and shoreline species have their own windows too.
This is not one global rule applied to all wildlife.
GenericWildlife / Snakes

What WildlifeSenses does
WildlifeSenses is the optional behavior addon.
It only affects proper animal models.
It excludes birds, Legendary animals, fish and domestics.
What it changes:
– higher hearing range
– higher ID range
– animals become highly perceptive
– panic triggered by hits
– panic triggered by bullets passing nearby
– panic triggered by bullet impacts
– panic triggered by gunshot noise within radius
Once panic starts, animals flee and keep fleeing much longer than normal.
What the LML files do
wildlifemanager.ymt
– reduces global wildlife density
– cuts down how crowded the world feels
– is the main reason the world is less full even before the script layer starts working
animalunalertedbehaviours.meta
– changes schedules by species
– moves species into different day/night windows
– makes the world less random by making certain animals tied to certain hours
These files are important because scripts alone do not fully control the ecosystem.
The mod works best because the tuning layer and script layer are doing different jobs.
Birds and Legendary animals
Birds are not modified.
Legendary animals are not modified.
This was done on purpose.
The mod is focused on normal wildlife, standard hunting flow, and open-world ecosystem density.
It does not try to rework everything in the game.
Installation
Drop everything into your RDR2 root folder, the folder where RDR2.exe is located.
You need:
– ScriptHookRDR2
– ScriptHookRDR2DotNet (link is in the window that appears before downloading)
– LML
The mod uses:
– scripts for the .NET dll files
– lml for the ecosystem tuning files
Compatibility
Anything that edits the same wildlife tuning files will conflict with this mod.
Main conflict files:
– wildlifemanager.ymt
– animalunalertedbehaviours.meta
So this should be your main wildlife ecosystem setup, not something stacked on top of three other spawn overhauls.
What this mod is trying to fix
The vanilla game throws wildlife at the player too often.
You can find too much, too quickly, at hours that make no sense.
This mod reduces that by:
– lowering density
– assigning real schedules to species
– enforcing those schedules
– making animals react better when hunted
So the result is not just “fewer animals”.
The result is:
less filler, more timing, more planning, and a much stronger reason to actually know what you are hunting and when you should be looking for it.
