The OpenMW team is proud to announce the release of version 0.51.0 of our open-source engine!

This release allows modders to create magic effects through our scripting API and introduces terrain vertex painting to our content file editor. It also fixes many Lua-related crashes and addresses a few minor annoyances with gamepad menu navigation introduced in the previous release.

Note: this only lists the changes and common issues to be aware of. Read the full announcement on our website.

Known Issues

• On macOS, launching OpenMW from OpenMW-CS requires OpenMW.app and OpenMW-CS.app to be siblings.
• [#7511] On Windows, a freeze may be reported if engine startup takes too long; ignoring the message is usually harmless, as it should eventually disappear, but if it doesn't, please share the freeze dump with us
• [#8233] Hardware antialiasing may cause driver timeouts on AMD GPUs of the RX 6000 and 7000 series; this is a driver bug AMD has yet to address
• [#8255] On Intel GPUs, the game may freeze visually while still responding to input. This is a driver bug; as a workaround, you may need to install an older version of the driver
• [#8464] Red tint on macOS. Some of it can be mitigated by enabling per-pixel lighting

Dialogue

New Features

• [#7297] Support for topic marking (MRK) files from Russian Morrowind; they override the keywords used for implicit topic highlighting
• [#8956] The iGreetDuration and fGreetDistanceReset game settings are now used in voiced greeting logic

Fixes

• [#7340] The Should Attack filter now passes for actors that are already in combat; this concerns actors that are not normally hostile, like guards
• [#8760] Implicit topic highlighting supports single-character topics
• [#8978] Added support for custom word separators required for Polish Morrowind topic highlighting (brackets and parentheses)
• Mixed implicit/explicit topic highlighting is properly supported

Gameplay

New Features

• [#8731] Hand to Hand Hit 2 sound is now used
• [#8801] More controller buttons can be used for actions

Fixes

• [#7605] Creatures that cannot equip items can use enchanted items
• [#8123] Various restrictions on equipping weapons during an attack were lifted (e.g., equipping ammunition)
• [#8692] The above extends to switching between enchanted items while casting a spell
• [#8765] Diseased actors may infect actors other than the player
• [#8847] Stretched collision box detection is more accurate
• [#8926] Weapon swish sound has been restored for thrown projectiles
• [#8929] Old effects now stick around for a frame when they're re-cast; this makes Weakness to Magicka increase its own magnitude
• [#8949] Instant effects are no longer applied twice
• [#8975] Stat modifiers are reset when werewolf modifiers are applied
• [#9062] Staggering an actor when they're unequipping a weapon and intend to re-equip it will no longer break their combat animation state
• [#9078] Preview mode is disabled when the preview if stand still setting is disabled

Graphics

• [#9001] Exclusive fixed-function pipeline rendering mode and the legacy lighting method have been removed

New Features

• [#6885] BC6H and BC7 compression are now supported for DDS files, as long as our OpenSceneGraph fork is used; this requires driver support and may not apply to all platforms
• [#8826] Sunlight direction is exposed to post-processing
• [#9030] Camera projection offset is configurable through Lua, which allows implementing techniques such as temporal antialiasing

Fixes

• [#6439] Fixed moon rendering: moon shadow colour and moon phase transparency are now used
• [#8351] Malformed NIF models are much less likely to cause freezes or crashes and will instead be gracefully rejected
• [#8657] Fixed a preloading-related crash on exit if startup was interrupted by non-graceful error handling (e.g., missing GUI layout files)
• [#8820] Non-carriable light sources like the scripted Trueflame light are properly detected again (0.50.0 regression)
• [#8854] Shaders from the post-processing chain that disable the sunglare will no longer disable it if post-processing is disabled
• [#8864] At storm wind speed, rain and snow properly produce ripples and no longer follow the camera, while heavy wind no longer makes rain look chaotic
• [#8884] Object paging no longer discards LOD centre data, making LOD level selection more reliable
• [#8924] Unnecessary hand-to-hand transition is skipped when you run out of thrown ammunition
• [#8930] Fixed a crash when a Gamebryo mesh has an extra data link that doesn't point to anything
• [#8983] Unequipping ammunition when preparing a ranged attack no longer cancels it immediately
• [#8985] Visual effects no longer make objects that use their model non-interactable
• [#8988] Particles are inverted vertically to match Morrowind
• [#8996] Fixed a crash when skinning data references a vertex that does not exist (the mesh will be rejected)
• [#9026] Thrown projectiles are rotated towards their movement direction again

Scripting: mwscript

New Features

• [#7830] Global script targets that don't come from a content file are now preserved (unlike Morrowind)

Fixes

• [#6494] Global variable reading is more consistent between ARM and x86_64 platforms. This ensures Raven Rock buildings don't show up earlier than intended on Android and macOS
• [#8129] Parsing of unquoted string literals as MessageBox button arguments is more consistent with Morrowind
• [#8732] MessageBox formatting supports more notation specifiers and flags

Scripting: OpenMW-Lua

For a full overview of the current state of OpenMW-Lua, please consult the scripting API reference.

New Context

• [#8987] Load context

Scripts that use this work-in-progress context run once, immediately after all content files are loaded. It exposes the loaded records as mutable data. It is related to—but not to be confused with—the existing custom record creation functionality (world.createRecord). Records injected via the load context are not serialised into saves.

The API reference provides the full list of exposed types and the types createRecordDraft is implemented for. New in 0.51.0:

• [#8791] Custom magic effect records (must be injected through the context)
• Custom ingredients are currently also exclusive to the context
• [#8342] Custom spells and enchantments can be created both via the context and during runtime
• [#8911, #8998] Custom container, creature, door, probe and static records can also be created during runtime
• Potion effect lists can be generated from a table

New Bindings

• [#2903] Barter gold
• [#8076] Dialogue filter conditions
• [#8725] Localised cell names
• [#8796] Potion autocalc flag
• [[#8816](https://gitlab.com/O...

This is the second round of release candidate (RC) builds of the upcoming 0.51.0 stable release, available for wider testing. Preliminary changes vs. the 0.50.0 stable release are listed in the description of the first RC round; further changes may occur in subsequent RC rounds and in the full release.

• [#8255] On Intel GPUs, the game may freeze visually while still responding to input. This is a driver bug; as a workaround, you may need to install an older version of the driver
• [#8464] Shader rendering is tinted red on Apple Silicon; enable per-pixel lighting to prevent that

Changes since RC1

• [#9069] Invalid effect loading is less strict; this lets Better Enchantments mod load again
• [#9077] The dialogue window no longer "wraps to bottom" when scrolling up
• [#9078] Preview mode is disabled when the preview if stand still setting is disabled
• [#9085] OpenMW-Lua: Fixed a freeze when teleportation occurs while item unequipment is scheduled
• OpenMW-Lua: Unequip handler properly unequips slots

The OpenMW team is proud to announce the release of version 0.50.0 of our open-source engine!

This round number release overhauls the gamepad experience, makes foundational steps in dehardcoding combat, further expands our Lua scripting API and, among the host of user interface fix-ups, introduces the highly requested quick item transfer.

Note: this only lists the changes and common issues to be aware of. Read the full announcement on our website.

Known Issues

• On macOS, launching OpenMW from OpenMW-CS requires ‘OpenMW.app’ and ‘OpenMW-CS.app’ to be siblings
• [#7511] On Windows, a freeze may be reported if engine startup takes too long; ignoring the message is usually harmless, as it should eventually disappear, but if it doesn't, share the freeze dump with us

• [#8255] On Intel GPUs, the game may freeze visually while still responding to input. This appears to be a recently introduced driver bug; as a workaround, you may need to install an older version of the driver. We've had reports of something similar happening on recent AMD drivers; the same workaround should apply
• [#8345] OpenMW-CS might crash randomly on Linux and macOS during global search or saving
• [#8464] Shader rendering is tinted red on Apple Silicon; enable per-pixel lighting to prevent that

AI and Pathfinding

Fixes

• [#6029] Awareness rolls of non-hostile actors are cached for 5 seconds to allow easier gain of Sneak experience
• [#7871] Immobile actors such as the Kwama Queen in Morrowind can initiate combat, however futile
• [#7979] Paralysed and knocked down NPCs can no longer use combat actions: to match Morrowind, they won't yell taunts or drink potions to get themselves out of their predicament

Fixes

• [#4437] Skinning base transformations and root bone are now used
• [#7799] Harvesting herbalism-enabled plants will no longer trigger expensive object paging chunk regeneration
• [#8176] Error marker loading is now thread-safe, preventing a potential crash when cell preloading and cell loading fail to find a model simultaneously
• [#8341] Magic glow will no longer disable parallax on the affected geometry
• [#8375] Moon phase cycle should now match Morrowind, e.g., "skip" days less often

Fixes

• [#8599] Non-ASCII paths using native encodings are properly supported in Morrowind BSA format

ESM Format and Saved Games

Contribution from S3ctor

We took care not to change the saved game format since 0.49.0. This means that you should be able to revert to 0.49.0 on your ongoing playthrough if you experience issues in the new release, although this is not recommended. For RC testing purposes, this also allows you to compare any behaviour between 0.49.0 and 0.50.0 easily.

• On macOS, launching OpenMW from OpenMW-CS requires ‘OpenMW.app’ and ‘OpenMW-CS.app’ to be siblings
• [#7511] On Windows, a freeze may be reported if engine startup takes too long; ignoring the message is usually harmless as it should eventually disappear, but if it doesn't, share the freeze dump with us
• [#8012] Combat music does not start during pause (e.g., during the dialogue that is scripted to start combat)
• [#8233] Hardware antialiasing may cause driver timeouts on AMD GPUs of the RX 6000 and 7000 series; this is a driver bug AMD is yet to address
• [#8345] OpenMW-CS might crash randomly on Linux and macOS during global search or saving; this is possibly a bug in Qt 6
• [#8464] Shader rendering is tinted red on Apple Silicon; enable per-pixel lighting to prevent that

Removed Features

• [#6624] Support for pre-0.45.0 saved games. Saves made in 0.45.0 up to 0.49.0 RC remain compatible. Use 0.48.0 to convert older saves
• [#7394] Virtual filesystem case-sensitivity support
• [#7720] Broken 360° screenshot support
• [#8214] Script blacklisting used in the --script-all option and OpenMW-CS script verifier, which served no purpose

AI and Pathfinding

Fixes

• [#2623] Actors prioritise Bound and Summon spells more
• [#4207] Actors prioritise healing spells and potions much less
• [#5065] Actors no longer attempt pathfinding while playing scripted animations
• [#5129] Actors back up smoother during ranged combat
• [#5413] Actors don’t yell taunts when engaging in combat against new allies of their current enemies
• [#5755] Friendly hit counter doesn't increment during combat and resets after it
• [#6313] High Fight rating allies no longer become hostile when the player has multiple allies
• [#6574] Navmeshes are no longer generated for very distant exterior cells, preventing a crash
• [#6932] Actors will no longer give preference to unreachable/invisible enemies in combat
• [#6964] Failed path smoothing can no longer cause the path to be rejected
• [#7064] Assaulted actors will realise they were assaulted even if they didn't detect the player
• [#7450] Improved obstacle evasion: more movement directions are used depending on the actor's animations
• [#7548] Actors can open doors teleported from a different cell
• [#7604] Creatures can properly use potions
• [#7639] Weapons are now considered useless if the actor's relevant skill is 0
• [#7646] Ranged attacks against allies make them hostile immediately
• [#7646] Magical attacks no longer prompt vocal friendly fire responses
• [#7647] Wandering interrupted by a greeting properly resumes
• [#7661] AI package assignments interrupt combat
• [#7685] Increased follow package activation distance to match Morrowind
• [#7723] Legalised assault and murder of vampires and werewolves
• [#7724] Guards attack NPC werewolves
• [#7758] Water-walking actors now properly consider their ability when pathfinding over water
• [#7959] NPC in-world book activations are handled as player book activations
• [#8132] Actors no longer face the player for greetings they won't deliver
• Absorb Skill/Attribute effects, like Drain and Damage effects, are no longer used when the relevant stat is zero and are prioritised based on how important the relevant stat is
• Alternate bound weapon spells aren't cast if a bound weapon is already in use
• Bound weapon spell priority takes weapon skill and ammunition into account
• Combat taunts are suppressed for On Self and On Touch spellcasting
• Escort packages terminate immediately when no destination is provided
• Wander AI properly supports crossing cell boundaries
• Weapon enchantments no longer receive spell priority multipliers when rated as weapons

Animations

New Features

• [#6009] Animation blending: optional, moddable animation transition smoothing for both NIF and Collada files
• [#6823] Animation layering support for Collada files (previously erroneously attributed to 0.48.0)

Fixes

• [#4127] Segments of attack wind-up and release are played continuously and are thus less choppy
• [#4610] Weapons can no longer be unequipped during an attack, which ensures bound weapons appear after spellcasting animation ends
• [#4742] Finished scripted animations no longer cause the same animations played afterwards as non-scripted animations to get stuck
• [#4743] Scripted animations that can't loop are no longer automatically disabled
• [#4822] Individual NPC body parts can have their own animations
• [#5062] Accumulated animation movement is no longer discarded in favour of manual movement
  This makes movement match Morrowind more closely, e.g. third-person camera sways for beast race characters
• [#5066] Playing an ongoing scripted animation group with a script no longer restarts it
• [#5371] Animations are no longer enabled for x prefix NIF files without their own x prefix NIF files when they are used as models
• [#6723] Collada files support head tracking and turn to movement direction and smooth movement options
• [#6992] Crossbow reloading animation is played on the entire body again
• [#6993] Shooting the last round of ammunition is no longer interrupted abruptly
• [#7042] Unexpected hit triggers are no longer processed – this stops some weapon animations from applying damage multiple times
• [#7611] Manual movement mode is no longer stuck after turning or jumping – this prevents idle sliding
• [#7636] Scripted animations persist through view mode changes
• [#7637] Scripted animations always restrict movement
• [#7641] Scripted animation loop count matches Morrowind
• [#7886] Ready Weapon transitions can reuse the animation
• [#7980] Paralysed actors no longer play blinking and talking animations
• [#8191] Re-enabled sheathed melee weapon animations
• [#8223] Movement takes priority over weapon animations for non-bipedal actors, allowing them to react to player movement when they're trying to attack
• [#8237] Spellcasting stance transitions are disabled again for non-bipedal actors (for now)
• Recoil/reloading weapon animation choice matches Morrowind

Configuration and VFS

Fixes

• [#6085] Replaced the remaining usage of Boost filesystem library with C++ standard filesystem library
• [[#6876](https://gitlab.com/OpenMW/openmw/-/issue...

These RC builds are outdated!
We do not provide support for outdated RC builds!

Visit the main Releases page to find the most recent RC build or corresponding stable release.

Windows 10 or newer is required to run the Windows build.

If you're running an AMD GPU and get frequent freezes (driver timeouts), disable antialiasing in the launcher. AMD is aware of the issue and is working on fixing it.

If you're running an Intel GPU and the game's visuals often appear to freeze, try to check if it still happens with the latest available driver for your GPU and downgrade the driver if it does. This also appears to be a driver-side regression.

Finally, we received many reports on Nvidia Windows driver crashes with unclear reason or connection. This is also suspected to be a vendor-side regression associated with post-50 series drivers, but we do not currently have a recommendation on how to deal with those other than to provide us with more crash dumps and openmw.log files.

Changes since RC8:

• [#8039] Fixed movement accumulation for actors that use Collada models on some builds compiled under LLVM
• [#8558] OpenMW-Lua: Light record color is now exposed as util.color rather than as a number
• [#8559] ESSImporter: Fixed selected spell/enchanted item and stolen item counter conversion
• [#8563] Improved handling of content files that are defined in the non-user version of openmw.cfg
• [#8567] Token replacement and relative paths work properly when the paths are passed through CLI
• Linux: Improved application detection for default shortcuts
• macOS: Packages now use Qt 6 like the other systems
• macOS: Reintroduced an Intel package
• Windows: Improved crash catcher error reporting in situations when crash dump creation fails

• OpenMW-Lua: Animation API is no longer accessible in menu and global contexts
• OpenMW-Lua: self:isActive binding properly returns false when the object is inactive
• Fixed undefined behaviour in the linear bloom shader that reportedly led to problems on Android
• Post-processing shaders can properly request a higher minimum GLSL version on systems that don't support UBO rendering, like macOS
• Weapon/shield attachment/detachment can once again happen at the very beginning of the (un)equipment animation

Changes since RC6:

• [#8273] Pathfinding message log level is now controlled by OPENMW_RECAST_MAX_LOG_LEVEL environment variable and is raised to Error by default
• [#8378] Fixed non-breaking space glyph rendering issues in dialogue and books: this further improves Korean bitmap font support

• [#8441] Main menu video is paused when the window is minimised to prevent a freeze upon reopening
• [#8462] macOS: Fixed crashes when the window is resized or a setting is tweaked in-game
• OpenMW-Lua: TargetPolygonNotFound pathfinding status is properly enumerated
• OpenMW-Lua: victim awareness option is properly supported in crime events
• Fixed a crash when shaders required to render ripples are unavailable or cannot be compiled
• Fixed graphic herbalism support for containers that only contain unresolved levelled items and containers that use skinned models
• Minimum point light radius has been raised to 16 to match Morrowind and prevent zero radius lights from turning very bright when classic falloff is enabled
• Pathfinding debug mesh write errors (e.g. when the files are written to an inaccessible location) can no longer cause a deadlock
• Restored --export-fonts command line option useful for testing bitmap font loading
• TES4 format quest record script variable subrecords are ignored: this allows esmtool to parse Fallout 3 DLC ESMs
• Windows: Config and data path detection errors are now reported
• Windows: Freeze catcher message has been revised and will disappear quicker if the application unfreezes
