OpenMW 0.50.0 RC2

This is the second round of release candidate (RC) builds of the upcoming 0.50.0 stable release released for wider testing. Further changes may occur for later RC rounds and the full release. Read the announcement blog post for more details. You may find the preliminary changelog of the coming release, excluding some of the following changes specific to this RC round, in the description of the first RC round.

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
• [#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 appears to be a recently introduced driver bug; as a workaround, you might 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

Changes since RC1

• [#8176] Error marker loading is now thread-safe, preventing a potential crash when cell preloading and cell loading fail to find a model simultaneously
• [#8710] Creatures can no longer break the game by casting an Absorb Skill spell
• [#8720] OpenMW-Lua: Fixed potential custom UI element corruption during error handling that could lead to crashes
• [#8721] Actions can be properly rebound to gamepad triggers again
• [#8724] Interacting with empty container menus should no longer cause crashes on assertion-enabled builds when the new gamepad UI is used
• [#8729] Encumbrance is properly updated when items are temporarily moved into/out of the inventory during barter again
• [#8734] Shield sheathing animations work properly again (issue introduced in 0.49.0)
• [#8737] Magic effects that cannot be applied to the target are no longer repeatedly applied if they're permanent
• [#8748] Building OpenMW under the newly released Qt 6.10 is now supported
• Linux: Fixed the generic tarball startup crashes of Qt-based applications on some systems, e.g. Ubuntu
• Improved BSA archive reading stability in various cases, e.g. for corrupted files or files where directory hash collision occurs

OpenMW 0.50.0 RC1

This is the first round of release candidate (RC) builds of the upcoming 0.50.0 stable release released for wider testing. Preliminary changes vs. the stable release 0.49.0 follow, and further changes may occur for later RC rounds and the full release. Read the announcement blog post for more details.

AI and Pathfinding

Contributions from Aussiemon, Capo, elsid and Evil Eye

Fixes

• [#5331] When Command effects stop, the affected actor will wander around their new location
• [#6029] Hostile actors will no longer engage in combat with the player if they have >=75% Chameleon active
• [#6029] The awareness rolls of non-hostile actors are now cached for 5 seconds to allow easier gain of Sneak experience
• [#7871] Immobile actors such as the Kwama Queen in Morrowind are allowed to initiate combat, however futile that would be
• [#7979] Incapacitated (paralysed or knocked down) NPCs can no longer use combat actions, so they won't yell taunts or drink potions to get themselves out of their predicament
• [#8433] Improved Wander pathfinding: actors will try to avoid moving into unreachable path grid nodes when possible
• [#8612] Actors no longer harvest herbalism-enabled plants non-stop when the Activate package is used

Configuration and VFS

Contributions from Duron27 and Evil Eye

New Features

• [#8077] Setting files are now saved when you exit the settings window, rather than only when you exit the game

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.

Fixes

• [#8333] Reading quest status subrecords no longer causes the rest of the quest record data to be discarded

Gameplay

Contributions from Aussiemon, Capo, Evil Eye, Foal and Kuyondo

Fixes

• [#6039] Next Spell now skips over items that belong to the same stack as the current item (it would previously get stuck if there were multiple copies)
• [#7622] Ranged attacks will now hit underwater if you're up close to a target (this matches Morrowind)
• [#7649] Sounds and visual effects of resisted effects no longer play
• [#7693] Potions and ingredients no longer visually end up back in the inventory for a single frame before getting picked up again for convenient consumption (0.49.0 regression)
• [#7996] Instant (zero-duration) effects can now act immediately. For example, instant Cure Poison can immediately cure the instant Poison preceding it
• [#8303] Underwater spell projectiles cast by objects will explode rather than immediately disappear (this matches Morrowind)
• [#8340] Multi-effect enchantment service price is now noticeably lower and should match Morrowind; it's now based on the accumulated strength of the final effect rather than the enchantment's overall strength
• [#8371] Silence no longer affects powers
• [#8383] Bound helm and boot effects cast on beast race characters are now interrupted immediately
• [#8399] Jail-induced major/minor skill increases count as level progress
• [#8404] Actors will no longer equip items to all slots when they want to replace their equipped light with a more appropriate shield. This allows the prevent merchant equipping option to work more intuitively for exterior merchants
• [#8446] Travel prices are calculated more accurately when the player has multiple followers: instead of calculating the offered price based on the base price for one character and multiplying it, the base price is multiplied first and then used for the offer
• [#8459] Spell prices are autocalculated properly for autocalculated spells
• [#8485] Base diseases bypass disease resistance
• [#8500] Fight rating adjustment crime reaction accounts for the number of items in the stolen stack
• [#8519] Pickpocket crimes will no longer be erroneously detected twice sometimes
• [#8540] Effects with no magnitude can no longer be resisted partially
• [#8557] Charm no longer influences the disposition clamping range
• [#8606] Floating-point imprecision should be less likely to mess with container capacity

• [#8680] Permanent effects are no longer erroneously restored on dead actors, e.g., when the player rests

Graphics

Contributions from akortunov, AnyOldName3, Aussiemon, Capo, Evil Eye, wareya and wazabear

Fixes

• [#4437] Base transformations and root bone included in the skinning data are properly used
• [#7799] Harvesting herbalism-enabled plants will no longer trigger expensive object paging chunk regeneration
• [#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
• [#8447] Non-vanilla threshold-based turning is no longer used for the player, fixing werewolf swimming turning animation getting stuck
• [#8490] Water normals exposed to post-processing no longer sometimes disappear when refraction is disabled
• [#8560] Global filtering settings are properly used for overridden textures of spawned magic VFX
• [#8593] Mipmaps are properly generated for post-processing render targets
• [#8598] Post-processing shaders are properly loaded from BSA files
• [#8610] Terrain normal maps now use the correct (DirectX or -Y) vertical convention
• Parallax should behave correctly for flipped geometry

Scripting: mwscript

Contributions from Aussiemon, Capo, Evil Eye and Kuyondo

New Features

• [#3769] GetSpellEffects now detects enchantments, similar to how a Morrowind Code Patch option works
• [#8509] FillJournal debug instruction, which adds all topics and journal entries into the journal

Fixes

• [#4885] Disabling actors through dialogue scripting should no longer cause crashes
• [[#8245](https://gitl...

OpenMW 0.49.0 Released!

After almost 3 years of development, we’re thrilled to release OpenMW version 0.49.0—our largest and most ambitious update yet!

This new release brings a hefty number of additions to our Lua scripting API, further polish to every single area of the engine—animations and lighting in particular—and it is the first one that goes beyond Morrowind! Be sure to read below for the full list of changes.

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
• [#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

Animations

New Features

• [#6009] Animation blending: optional, moddable animation transition smoothing for both NIF and Collada files

• [#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

• [#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...

OpenMW 0.49.0 RC9

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: 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

• [#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
