Bugs remaining

  • SayToDone will not trigger if the actor is not in the same cell as the player regardless of quest item or persistence.
  • EGM files will not load correctly unless in a BSA file and/or overrides negate them.
  • RemoveAllItems does not run OnUnequip blocks and causes effects to be left on the player
  • RemoveAllTypedItems does not run OnUnequip blocks and causes effects to be left on the player
  • Multibounds have a bug where the culling flickers when used with vis planes. This might be due to the flickering issue of overlapping alpha primitives and other alpha objects. Roombounds do not exhibit the culling problem but do also exhibit the issue with objects that have alpha.
  • Weapons and armor with OnEquip and OnUnequip blocks don’t fire when RemoveAllItems or RemoveAllTypedItems is used
  • Projectiles (Grenades) with VATS targetable flag can be targeted in VATS, but always have 0 chance to hit in both games. Confirmed working on PS3 and XBOX 360
  • Projectiles that use Full Ballistic Flight Modeling (Non hitscan projectiles) will not use water impact decals even if defined in the impact data set.
  • Caution or Combat mode does not clear when the player moves to a cell which has no alerted actors, and can remain active even though all enemy actors are dead Sometimes it stays active until the game is reloaded (happens in both games) - partially fixed by JG
  • Creatures that have a membrane shader (Aliens) will double any DR effect added to the base creature form as an actor effect. This may apply to any NPC/Creature, not yet verified (happens in both games) - note this was also a bug with DT in New Vegas and was fixed in patch 1.3
  • NPCs wearing armor with enchants get applied every time they are loaded and stack infinitely (possibly because no recovery flag on the effect or no "has effect" check)
  • References (non talking activators) set to be talkers via SetTalkingActivatorActor have no distance attenuation (works in Fallout 3) - probably intended in NV, would be nice to have this selectable somehow
  • iSneakLevelBonus creates an issue when the player is > the level of the actor/creature and results in it being harder to sneak by them, 0x642ED0, the multiplication results in a negative modifier
  • AI does not always process correctly unless the player is in the cell, moves through a load door, or fast travels regardless of no low level processing flag for many package types: sleep, find, patrol, eat. It is as if the processing level is having the wrong one chosen (works in Fallout 3)
  • Actors with lock/unlock door packages do not check the doors in the cell they are in for ownership and will lock them even if owned (works in Fallout 3, may be related to above)
  • AI dialogue package Once a Day flag works inconsistently (Rivet City, works in Fallout 3)
  • Tree LOD does not process correctly and is not used because of this, " _flat" files are still loaded randomly in the worldspace inside uGrids, seems to be several issues related to NV changing the grass draw distance to a max of 3000 (works in Fallout 3). (Kind of fixed by LOD Fixes and Improvements
  • Animated imposters stop working correctly in the outer ring of uGrids (bizarre!)
  • The idle manager behaves oddly picking the same idle constantly (possibly condition issue)
  • If an actor template is in a leveled list, the actor template will almost always be chosen (NV only, works in Fallout 3)
  • Actors with the Aggro Radius Behavior flag will not execute their packages if the player is near, even when they are not hostile, after an indeterminate amount of time has passed since the game began (constant aggro)
  • Strange teleportations occur with Havok items in cells which exceed Havok bounds and a mesh also exceeds the bounds. This can also be triggered by setting a moveable static object to enable state opposite of the player and placing it outside Havok bounds (happens in both games)
  • Actors and Projectiles sometimes ignore Havok or bounds when culled from the camera frustum or initially loading a cell
  • GameMode scripts will not run on crafted items until dropped and picked up
  • Occasionally editor primitives can be seen in the worldspace (collision spheres observed, happens in both games)
  • Weapons with looping sound will occasionally play the sound when nearby, after a save game is loaded upon player death. Loading the save manually again will stop it.
  • Disabled objects with looping sounds sometimes still play the sound
  • Creatures with idles in other cells can sometimes be heard
  • Stonewall does not reduce damage against creature attacks since they are classified as neither melee nor unarmed attacks.
  • StartCombatResponse does not check other actors and makes the original actor say the line when they shouldn't.
  • Havok bounce physics set on NIFs with the Restitution value only bounce very occasionally when a specific area of the NIF impacts the ground in a certain way, as a result NIFs with sphere primitives like basket balls have almost no ability to bounce at all and drop like rocks. (Works in Fallout 3)

Notes

  • Conditions on Quests and Dialogue Topics (voice types) are not merged at runtime which can cause various problems with dialogue topics, (proper patches have to be made for this). Not really an engine bug, but worth noting.

  • Impact decals only appear on the first three shape blocks of armors and creatures (happens in both games) - debunked by Stewie
