Build 41, also known as The Animation Overhaul, has been titled as such due to its major overhaul of the entire animation system. This new system has been made known to the public since mid–late 2015. Unfortunately, due to technical difficulties and developer inexperience to create a simple, reliable and easily moddable animation system, meant several new experienced employees were employed to work solely on a highly versatile and easily moddable animation system. Whilst this new system was being developed, the main development team continued to work on new features, with the most notable being vehicles (build 39) and weather (build 40). Whilst the development of the animation system appeared to be slow, this update has been the largest change to the base code in all of Project Zomboid's development, with the second being the addition of vehicles.

Along with the new animation system, the update will also include new player models, weapons and tools (models), skills, clothing, a new/updated combat system, gamepad/controller improvements (moved to build 42 due to technical issues), two new challenge maps, reflective and animated water and dynamic puddles.

IWBUMS Build 41.26

Forum: IWBUMS Build 41.26


  • Revamped mod system:
    • Updated the Mods screen. The mod description is displayed for the selected mod on the right side of the screen, instead of in the list of mods. Other details such as the ID, Workshop ID (if any), installation directory, and any posters are displayed on the right.
    • mod.info can have multiple poster= lines to specify multiple images in the Mods screen.
    • mod.info can have multiple description= lines which add to the total description.
    • The New Game screen has a button to choose which mods are enabled for the new game.
    • Each savefile has its own list of mods saved in a file named mods.txt. mods.txt also has a list of map folders that is used in cases where parts of different maps overlap each other.
    • The Load Game screen displays the map folders and mod names used by the selected savefile. Since old savefiles do not have a mods.txt file, all currently-enabled mods are used when loading an old savefile. After loading an old savefile for the first time, the mods for that savefile cannot be changed, except by editing or deleting mods.txt. The old Zomboid/mods/loaded.txt file has been replaced by Zomboid/mods/default.txt. This file contains the default set of enabled mods that will be used when creating a new game. The default mods can be overridden when creating a new game in the New Game screen. default.txt also contains the list of map folders that was previously saved in options.ini (the old "mapOrder" setting that was used to deal with overlapping maps). If there are no map-overlap conflicts, this list of map folders is empty.
  • Added bBeingSteppedOn IsoZombie GameVariable to test if a player (or zombie) is standing on a prone zombie. Originally I was going to use this to prevent fake-dead zombies turning over when the player is standing on them.Prone zombies won't stand up if another zombie is standing on them.
  • Changes on character creation:
    • Can now save/load outfit (clothing, m/f, name)
    • Can now select texture when item using multiple texture but no colors (jeans comes in 3 colors, but a random one was choosen everytime).
  • Tweaked washing clothes at sinks:
    • Clothing is washed one item at a time.
    • Items are washed in order from least-bloody to most-bloody when Wash > All is chosen.
    • Context-menu tooltips display the required amount of soap and water.
    • The correct amount of soap and water is used.
  • Added a display option to specify which modifier key used in combination with the mousewheel cycles between containers in the inventory and loot windows. The default is Shift.
  • The "Walk To" context-menu command displays a cursor to specify the location to walk to. This allows the player to click multiple times without having to choose the "Walk To" command again, making long jaunts through forests easier.
  • Items are now placed onto an adjacent not-full square when dropping items on the ground. This is needed since the loot window displays items from the surrounding 3x3 squares, and each square can only hold 50 weight.
  • Added an option (under Accessibility) to drop items near the center of the square the player is standing on, rather than exactly where the player is standing, for neat freaks.
  • Items now transferred from lightest to heaviest, to maximize the number of items that will be transferred.
  • Animation now plays when transferring items between main inventory and equipped bags.
  • Vehicle-headlight distance and intensity are based on the part condition instead of being randomly set when the vehicle is created. Headlight width is also based on part condition. The Focus Up and Focus Down context-menu commands which changed headlight width were removed.
  • Updated community translations.
  • Added a nag panel that pops up the first time the user tries to access the Mods screen.
  • Added the word "ERROR" to the little red box of doom.
  • Zombies can now have random bandages (bloody!) on them, thanks Captain Australia on reddit for the idea!
  • Overlays updated


  • Limited the forces applied to vehicles when driving over corpses to prevent liftoff.

  • Allow the player to drop items while moving, to avoid unfair deaths
  • Changed Screws weight to match Nails.
  • Changed IsoGameCharacter.maxWeight from Integer to int.
  • Reduced the damage to headlights from hitting zombies.
  • Added more attack prediction for the standing/on ground zombie detection.
  • Moved Tailoring perks from Survivalist to Crafting sub category.
  • Changed Flint knife to Stone knife (using a sharped stone).
  • Increased Digital Watch spawning rate.
  • Lowered chance of some helmet removals.
  • Can now attach meat cleaver to the belt.
  • When a car spawn in zed stories (police, fireman..) key of the car can be find on one of the zombie spawned with it.
  • Lowered general condition of car spawning in house stories.
  • Renamed Key in House keys.
  • House key can now spawn in kitchen counter.
  • Fireman in burnt house stories now spawn a firemen vehicle.

    • changed clothing wetness/drying, added perspiration and body heat working the layers from inside to outside
    • added clothing insulation values to new clothing, Clothing insulation can be set from 0.0 to 1.0
    • added clothing wind resist, decreases windchill effect, can be set from 0.0 to 1.0
    • added clothing water resist, 1.0 fully stops soakthrough (example poncho) lower value slows it down
    • added time penalty for timed actions when hands/arms are very cold
    • added bodypart widget to protection panel
    • changed PlayerClimateDebug to show debug stuff for thermoregulator now
    • added BodyPartContacts, can be used to determine which body part connects to another
    • added distance to core, skinsurface percentage and umbrella mod to BodyPartType
  • Added Clothing Repair:
  • Right click an item to add/remove patches to clothing.
  • Adding a patch to a hole removes it, otherwise it simply gives you defense bonus (need to add more insulation to them if simply upgrading).
  • Quality of the defense depend on fabric used & tailoring skill.
  • In coming weeks a UI will be made to inspect clothing so it'll be less clicky through submenus.
  • Changed how ripping clothing works to make it easier to update when new clothes are being added.
  • Can now rip leather/denim stuff to get strips (requires scissors).
  • Boosted overall thread spawn rate, can also get leather strips when disassembling leather stuff (couch etc.)
  • Patch textures currently all the same no matter the fabric used, they are placeholder textures.
  • Gun improvements:
    • Tweaked hit chance with guns: should be easier and have a way more 'linear' feel toward aiming level now.
  • Improved zombies sprinter:
    • They now sprint only if they have a target, otherwise they just walk.

    • Controller X button now transfers items from the player to whichever container is displayed in the loot window, instead of to the floor.
  • Saving and logs:
    • Added DebugLog.txt file to logs.zip. This file is contained in /debug-log/ directory in archive.
    • Checked that vehicles.db file is saved in logs.zip. This file is contained in /save/ directory in archive.
    • Added saving last save when the game starting. Those files are contained in /save_old/ directory in archive.
  • Water improvements:
    • Added WaterZones on the docks and boathouse north of Westpoint to fix rendering with the water shader. It isn't 100% fixed; the tiles that provide thickness to the docks aren't visible, and there's a 1-tile glitch where the dock meets the shore.
    • I changed the water-shader code to render in two passes, first the solid water tiles, then the regular tiles, then the shore tiles. It fixes some tiles being hidden on the docks/boathouse north of Westpoint, and the railway bridge east of Westpoint. Previously you couldn't see the transparent floors on the edges of the railway bridge because the water covered them.

    • Fixed puddle data rendering. This was to fix a bug when opening/closing a door using a controller, puddles would appear briefly in a 3x3 area around the door. It didn't happen when using the 'E' key, strangely. I think the puddles rendering isn't thread safe though, the main thread could be updating IsoPuddlesGeometry.pda/etc while the render thread is reading them.
    • Fixed the second container in the loot window being auto-selected instead of the first when using a controller. IIRC the floor used to be displayed at the top of the list of containers in the loot window.
    • Fixed some garage doors with walls behind them in cell 25,31.
    • Fixed zombies inherit some other room distributions, making easy to farm some items by luring zombies into specific rooms.
    • Removed tutorial popup message for new players.
    • Fixed entering a vehicle sometimes taking longer than it should. This seemed to happen when the player was playing a turning animation and entered the vehicle.
    • Fixed rendering of wall vines being affected by the old circle-stencil.
    • Added a delay-before attack animation to the zombie "attack" state in 100% unfair instant pounce situations. The animation lasts 1/2 second. This replaces the 'grace' period from the last patch.

Changed WaterDrip sound to only play on IsoFlagType.waterPiped sprites with water (so they won't drip after the water shuts off, unless connected to a water source). Yuri found that when there are puddles on the ground, there are way too many WaterDrip sounds playing. That was due to IsoObject.hasWater() returning true on squares that have puddles.

[Bug Fix]

  • Now treats aiming/strafing as a zero-momentum state, like idle.
  • Turn180 now uses idleToRun180 instead of runToTurn180 when going from strafe -> run in the opposite direction of travel.
    • Only blends (with animations) to defaultWalk/Run/Sprint if isTurningAround==false
    • Uses animation-less transitions otherwise. This prevents the transition anims from doubling up with the turn180s anims.
    • ZNetFriends continues pinging in singleplayer, possible it's one source of FPS drop
  • Failed to Poll Device spam should be hidden, may be source of FPS drop for those with Blutooth or other wireless hardawre
  • Vehicle will continue moving after its tire is burst
  • Increase quality of Tires on cars to at least 20-30% in Survival mode
  • Fixed missing bob/bob_idle on Turkish systems.
  • Fixed AnimationSet lookup bug with Turkish locale ("Idle" -> "idle").
  • Fixed EmptyStackException in IsoSpriteInstance.get().
  • Fixed player not starting without clothes in AReallyCDDAy.
  • Fixed custom icons for clothing and containers being lost after reloading a game.
  • Fixed exception cleaning blood with a Bath Towel.
  • Fixed exception loading shotguns (or any gun without a magazine).
  • GrabItemAction transfers multiple items at a time similar to InventoryTransferAction.
  • Transferring large stacks of items should no longer lower fps.
  • Fixed losing ammo when creating a sawn-off shotgun.
  • Fixed resize behavior of the Customize Character screen.
  • Fixed combining InventoryTransferActions when the source and destination containers aren't the same.
  • Changed "version 110" to "version 120" in some shaders that use functions in const expressions.
  • Fixes to MainThread/GameThread crash handling.
    • A crash in RenderThread no longer locks-up the game.
    • Uncaught Errors now get absorbed, logged, and an attempt is made to preserve save data.
    • Added uncaught exception handlers to MainThread, GameThread, and any other internal threads I could find.
    • Added default uncaught handler for any external threads.
    • Added custom handler for MainThread, sets bGameThreadExited and signals the RenderThread.
    • Added custom handler for RenderThread, sets m_isCloseRequested, zaps any waiting queues, and waits for MainThread to save and close.
  • DebugOptions
    • Added testThreadCrash mechanism, used to fire a crash on-demand, remotely from AnimZed.
  • Run -> Strafe -> Run now keeps to a straight line of travel. No longer does the strange arc movement during transition
  • Strafe -> Run transitions now only use transition anims if at not turning more than 90 degrees.
  • Strafe -> movement transitions updated to correct targets when isTurning90/Around.
  • Fixes to odd arc turns during transitioning from walk -> strafe
  • Fixed Brawler and Builder playstyle options in menu to stop them launching Survivor by mistake
  • Crash-fix for when getVectorFromDirection is given a null vector.

  • Hide "Opening Hours" since it performs poorly.
  • Possibly fixed rainbow-colored bodies on Mac OS.
  • Possibly fixed failure to load bob/bob_idle animation on Windows using the Turkish locale.
  • ModelManager.loadAnimsFromDir() calls ModelManager.loadAnim(ZomboidFileSystem.getAnimName()).
