This is an example set up for a 247 store. These files were exported from codewalker and then commented to create these instructions.
Importing these files in to the game will most likely not work, since the 247 store is already there.
You can reverse the 247 file contents and values using the below formulas to see and recognize patterns, and create your own custom interior audio files.
All Integers greater or lesser than Int32.Max/Int32.Min must be converted to Int32.
You can use the following: $number & 0xffffffff
Below are references to comments in the files and their purpose.
We've found ntOffset to not matter, set it to 0.

The formula to generate an occlusion hash is:
{$archetypeName.Hash} ^ Math.floor(({$mlo.pos.x} * 100)) ^ Math.floor(({$mlo.pos.y} * 100)) ^ Math.floor(({$mlo.pos.z} * 100)) & 0xffffffff
File name is the Occlusion Hash
This is the source room ID index as seen in the <rooms> key in the ytyp file.
This is the destination room ID index as seen in the <rooms> key in the ytyp file.
This is the portal ID based on the index of the <portals> key in the ytyp file.
Important note: this is the index of the <portals> list AFTER it has been filtered based on RoomIdx.
Range from 0.0 to 1.0.
Entity hash, of the door, window, etc.
If there is no objects attached then the PortalEntityList needs to be empty.
The PathNodeList is used describe audio paths between two rooms. That can be rooms directly connected such as Room1 -> Portal0 -> Room2 (direct link) or rooms connected through multiple rooms and portals like Room1 -> Portal0 -> Room2 -> Portal1 -> Room3 (bridge link). We'll call each entry in this list a PathNode.
A "direct link" only links rooms together explicitly, meaning that even if you create Room 0 -> Room 1 and Room 1 -> 2, audio is not routed from Room 0 -> Room 2 as there is no direct link or a bridge link.
This key is unique per direction and is generated by using this formula: (StartRoomHash - EndRoomHash).
Below you can find a list of examples of key generation for
Room 0 -> Room 1
Room 1 -> Room 0
Room 1 -> Room 2
Room 2 -> Room 1
NOTE: WHEN GETTING JOAATS - ALWAYS USE LOWER CASE!
GTA V uses 1-5 "channels" between each room, so the actual value you'll be using in the PathNodeList.Key is whatever the result of (StartRoomHash - EndRoomHash) is + 1 ... 5. That means that you'll have to create N amount of PathNodes of each PathNodeList.Key. We usually just create three nodes. That means that for Outside -> Room 1 which is 2124924645, you'll have three PathNodes, with the PathNodeList.Keys [2124924646, 2124924647, 2124924648].
| Name | Ytyp Name | joaat |
|---|---|---|
| Outside | limbo | joaat("outside") = 3086856661 |
| Room 1 | V_66_ShopRm | joaat("V_66_ShopRm") = 1569794095 |
| Room 2 | V_66_BackRm | joaat("V_66_BackRm") = 462608346 |
room1Hash =
occlusionHash ^ Room 1=> 1690616543 ^ 1569794095
= 961932016
PathNodeList.Key =
Outside - room1Hash=> 3086856661 - 961932016
= 2124924645
room1Hash =
occlusionHash ^ Room 1=> 1690616543 ^ 1569794095
= 961932016
PathNodeList.Key =
room1Hash - Outside=> 961932016 - 3086856661
= -2124924645
room1Hash =
occlusionHash ^ Room 2=> 1690616543 ^ 1569794095
= 961932016
room2Hash =
occlusionHash ^ Room 2=> 1690616543 ^ 462608346
= 2136347909
PathNodeList.Key =
room1Hash - room2Hash=> 961932016 - 2136347909
= -1174415893
room2Hash =
occlusionHash ^ Room 2=> 1690616543 ^ 462608346
= 2136347909
room1Hash =
occlusionHash ^ Room 1=> 1690616543 ^ 1569794095
= 961932016
PathNodeList.Key = room2Hash - room1Hash
=> 2136347909 - 961932016
= 1174415893
When using and adding these keys, you will increment by 1 from the base value. They also need to be in an order where a key must be declared before it can be referenced in PathNodeKey.
As previously mentioned, a PathNodeList.Key must be unique Add <Items> in to this list to create multiple audio sources (in and out) for the same room.
If this value is 0, its a direct reference to the PortalInfoIdx entry.
If this value is not 0, it is a direct reference to another PathNodeList.Key value. This is used to link audio through multiple portals.
Reference to a PortalInfoList entry by index.
Native GTA uses the same files for multiple interiors. You only want to reference the ones you are interested in.
This is very straight forward..
File: audio/v_shop_247_mix.dat15.rel.xml
Set <Name>$Dat15_Scene_Name</Name> to whatever
Set <Patch>$Dat15_Patch_Name</Patch> to whatever
Set <Name>$Dat15_Patch_Name</Name> to the value you set in Scene.
In you can add definitions for ambient zone sound (limits or boosters(?)) - Check existing .dat15 for all the different variants you can use.
Create an <Item>$AmbientZoneName</Item> with a name for the AmbientZone and add it to
You can basically use most of whatever is in the template, but you'll have to change a few things.
Set OuterPos and InnerPos to the position the Ytyp and then you can use the following formula to calculate the size OuterSize (You should probably pad this with with 1.0) and InnerSize. Get the Minimum and Maximum Extents and use it to calculate the size of the box.
Set the name of the <Name>$AmbientZoneName</Name> to the name you decided in the AmbientZoneList($AmbientZoneName)
Set the name of <UnkHash1>$Dat15_Scene_Name</UnkHash1> to a name you set in Dat15
Vector3 boxSize = extentsMax - extentsMin;
Vector3 center = new Vector3(extentsMin.X + boxSize.X / 2, extentsMin.Y + boxSize.Y / 2, extentsMin.Z + boxSize.Z / 2)
<OuterPos x="center.X" y="center.Y" z="center.Z" />
<OuterSize x="boxSize.X" y="boxSize.Y" z="boxSize.Z" />
<InnerPos x="center.X" y="center.Y" z="center.Z" />
<InnerSize x="boxSize.X" y="boxSize.Y" z="boxSize.Z" />
Hashes contains the hashes of the staticEmitters - I wont go into detail about them.
Name needs to be the archetype (e.g. v_shop_247)
For each room in your interior you'll need to add an $WhateverYouWantAsANameForYourRoom in , the name you choose however has to be the same name in "InteriorRoom".
File: audio/v_shop_247_game.dat151.rel.xml
For each room you have in your interior you have to create an entry with this (use this template basically and change anything with $)
<Item type="InteriorRoom">
<Name>$WhateverYouWantAsANameForYourRoom (from Interior)</Name>
<Flags0 value="0xAAAAAAAA" />
<MloRoom>$MloRoomName</MloRoom>
<Hash1>$AmbientZone</Hash1>
<Unk02 value="0" />
<Unk03 value="0.5" />
<Unk04 value="0" />
<Unk05 value="0" />
<Unk06>null_sound</Unk06>
<Unk07 value="0" />
<Unk08 value="0" />
<Unk09 value="0" />
<Unk10 value="0.55" />
<Unk11 value="0" />
<Unk12 value="50" />
<Unk13 />
<Unk14>hash_D4855127</Unk14>
</Item>
You can tinker with the values, we haven't had the time to note down what they do exactly.
Unk04 Reverb?
Unk05 Echo
Unk06 is the "room sound" or whatever (tone master?)
Unk13 is the static emitter hash
