Universal Modder でバルダーズ・ゲート 3 を MOD する

バルダーズ・ゲート 3 にはナレッジベースでも特に詳しいノートがそろっています。新しいコンテンツだけでなく、モッダーが実際に時間を使う地味な作業まで扱っています。500 個の MOD のロード順を手作業で管理し、第 2 幕を止める 1 体の NPC を見つけ、MOD 同士の互換性を直す、といったことです。

Universal Modder は Baldur's Gate 3 にどう取り組むか

BG3 の MOD はデータとアセットの MOD です。ステータスファイル、Osiris のスクリプト、.pak パッケージ、そしてメッシュには Blender での GR2 の往復変換を使います。エージェントは modsettings.lsx と mod.io の購読を扱い、問題が起きたら pak を二分探索します。

ローダー / ツール用途
公式 MOD マネージャー / mod.io多くの MOD をゲーム内でサポート。
Script Extender + pak MODゲーム内マネージャーでは届かない深い変更に。

エージェントが使ったツール: Blender 3.6 LTS + niftools addon 0.1.1 (NIF import) · Blender 4.0.2 + Norbyte dos2de_collada_exporter · LSLib Divine 1.20.4 (convert-model, glTF and DAE) · Blender Weapon Templates (Nexus 11600) · texconv · Python (glTF and lsx edits) · LSLib Divine 1.20.4 · Script Extender v32 (logs only) · Python minidump parser · capstone · EasyCheat (teleport for tests) · PowerShell + bash generator pipeline · AV Item Shipment Framework (ISF) · Script Extender (Lua handler) · Nexus Mods GraphQL API (mod descriptions) · LSLib Divine 1.18.7 / 1.20.4

Weapons: porting a Skyrim dagger and scabbard, fixing a modded sword's sheath height with a Dummy_Sheath bone, and visible stowed shields for modded shields

Three weapon jobs in one personal mod. (1) The dagger and scabbard from the Skyrim SE mod "Hravna - Dagger of the North" by Danp (for personal use) became a usable BG3 dagger plus a worn scabbard that sits where the sheathed dagger lands on the hip, with the Bandit belt from wesslen's BG3 mod "Modular Equipment" as its strap. (2) The Deathwyrm longsword…

  • Weapon or scabbard lying flat on the floor, "following the character like a windsock".
  • Scabbard far behind the character, underground.
  • Scabbard on the wrong hip.
  • Scabbard and sheathed blade drift apart when walking.
  • Dagger invisible after conform.
  • Sword invisible after conforming to a vanilla longsword "to borrow one bone".
  • Sword invisible after adding a Dummy_Sheath JOINT in the DAE.
  • Bone moved the hand pose instead of the stowed pose.

Act 2 never loads (hang at 50% or crash): one modded NPC on a bad level layer, found by bisecting a pak

Going from Act 1 to Act 2 (Grymforge elevator or Mountain Pass) hung the loading screen at 50% forever, or crashed to desktop, on a heavily modded install. Eight static scans of all 524 paks found nothing. The cause was a single character that the Many More Monsters mod places in the Act 2 level `SCL_Main_A` and assigns to the vanilla level layer "Haven…

  • A truncated scan reads as a clean scan.
  • Proximity is not causation.
  • Base rates.
  • Absence inferred from a count.
  • Script Extender logging itself causes stalls.
  • Steam "Verify integrity" removes the Native Mod Loader.
  • Shell traps that cost passes:

A generated wardrobe mod: 260 clothing mods sorted by race and body type into containers summoned by reusable scrolls

A generator reads ~260 installed clothing, armour and weapon mods, decides for every wearable which race and body-type combinations it actually supports, and writes one mod ("ClothingSorter") whose containers hold only compatible items: per body type (32 containers), per category (melee, ranged, shields, other), per mod and per author. Nothing is spawned…

  • Truncated names collided.

  • Scroll applied Guidance and played its cast effect.
  • Changing UUIDs bricks saves.
  • Items silently missing from the parse (items=0).
  • Mod identity read wrong.

  • Controls locked after a big spawn, world still running.

Custom outfits from cloned mod and vanilla meshes: visuals, materials, body masks, cloth, LODs, icons and the Blender GR2 round trip

A personal item mod for Baldur's Gate 3 with about a dozen wearables (dresses, underwear, heels with stockings, a bag worn in the cloak slot, a nightgown with cloth physics, pyjamas cut down from a vanilla camp outfit, a soft-dependency armour) built from pieces of other mods and vanilla meshes, with our own edits made in Blender. Everything is data and…

  • Underwear rendered nothing, even pointing at vanilla visuals.
  • Edits had no effect.
  • Item exists but is invisible everywhere.
  • Invisible after a re-export.
  • Removed parts still there, some untextured.
  • Cloned dress renders but has no cloth physics.
  • Item disappears at a distance / all LODs draw at once.

Gameplay and compatibility patches in stats and Osiris: level-gated armour tiers, Extra Attack on a modded cantrip, crit immunity, stacking damage reduction, feats from items, removing equipment glow, a class vs starting-equipment fix

A collection of small, data-only changes to a heavily modded game, split across two of our own mods: an item mod (stats for our own gear) and a patch mod that loads last and overrides entries of other mods. Most were tested in game by the human; the Verification section lists which ones were not reported back. The recurring lesson: copy the exact form of…

  • Our damage reduction applied but did not stack.
  • "IF(CharacterLevelGreaterThan()) is invalid in Boosts" was wrong.
  • Higher tier gave lower-rank effects at level 3.
  • Armour showed as "Clothing", added Dex to AC.
  • Spell from a usable item could not be cast, auto-deselected.
  • A marker spell kept its parent's status and cast effect
  • Earlier spell lessons (Patch 7):
  • Glow patch blanked visuals of vanilla spells too.

Running a 500+ mod load order by hand: modsettings.lsx rules, recovering a wiped order from a save, mod.io re-subscribes, game-folder files and conflict diagnosis

How a ~530-mod Baldur's Gate 3 install was kept working without a mod manager: what `modsettings.lsx` and `meta.lsx` must look like, how the game identifies a module, how to rebuild a lost load order from a save, why the in-game manager and mod.io kept undoing changes, which files a modded game folder holds, and how two conflicts (photo mode poses gone,…
