Each section of MotherBase/a FOB is called a cluster.

Each cluster may have up to four platforms. Platforms may also be referred to as plants (which may be abbreviated to plnt).

Each platform may have 1 unique or 4 divisions.

A clusters grade is the number of platforms built for it, with 0 being no platforms for cluster. Plant Id may be 0 indexed or 1 indexed depending on the function using it, usually if the function is exe based it will be from 0, lua based from 1. With the lowest Id representing the unique platform for the cluster.

Cluster Ids

May be referenced in files and lua either 0 indexed or 1 indexed depending on the function using it, usually if the function is exe based it will be from 0, lua based from 1.

In some cases in lua a list of cluster names may be used in a different order/will not conform to the standard clusterIds.

When used as part of the name uses cl%02d format, 0 indexed, ex Medical is cl04

Divisions

Common platforms are divided into 4 divisions, unique covers all 4/central area of plat

Reference to the fpks seem to only be in exe:

%s/pack_division/%s_%03d%01d.%s

ex: /Assets/tpp/pack/location/mtbs/pack_division/mtbs_division_0010.fpk

params:

1. %s: locationPath: /Assets/tpp/pack/location/mtbs/
2. location div str?: mtbs_division
3. %03d: divisionId: 001
4. %01d: subdivision? variant?: 0
5. %s: extension: fpk

dv_0000

• 0000 - flat base - used for container storage
• 0010 - rectangular blocks of ducting with grated walkway on top
• 0020 - low walkways
• 0030 - mix of some larger weird shaped building with overhang and studd
• 0040 - lotsa small silos
• 0050 - 3 big silos
• 0060 - the pits, two covers closed, one open - used in the kid falls-down-a-well story beat
• 0061 - the pits, all covers open - used in the kid falls-down-a-well story beat
• 0070 - overall raised connected blocks with under walkway and minipit
• 0080 - tall tower and lower pit
• 0090 - tall drilling righ thing
• 0100 - vehicle/large elevator, has room to lower flush with platform ground level
• 0101 - vehicle/large elevator, actually flush? or without elev? TODO: no actual use on MB, any uses in demos or FOB layouts??
• 0110 - dual division: rectangular blocks similar to 10, but also low walkway, dual/connected divisions
• 0111 - not sure if separate or some kind of overlay (look at texture vs 110 vs actual mother base map), if so it’s not in line with 0110 even though it is on ui
• 0120 - dual division: diagonal multi level walkway, dual/connected divisions
• 0121 - overlay for 0120? or is this how they handle the dual divisions (see 0110,0111), but then see 0130, TODO: check if there actually is a 0131 rather than just going by ui files
• 0130 - seems to be same as 110, but the actual combined ui texture, and it’s also a larger resolution?
• 0500 - zoo pit that takes up 4 divisions
• 0510 - ?? zoo again I guess? dual division?

uq_0000

• 0000 - Command
• 0010 - Combat
• 0020 - Develop
• 0030 - Support
• 0040 - Medical
• 0050 - Spy
• 0060 - BaseDev
• 0070 - Separation / quarantine
• 0080 - Zoo

Layout Codes

Set by vars.mbLayoutCode layouts are positions and orientations of clusters and platforms.

For a given range of a layout there is actually four layouts, indexed from 0 to account for the available connections from the center/command cluster depending on the number of platforms built for that cluster.

FOB events run on ‘fully built’ bases, so the highest number in a range (i.e. layouts 10-13 -> mbLayoutCode == 13)

vars.mbLayoutCode is driven by MotherBaseStage.ModifyLayoutCode(layoutCode), via TppLocation.ModifyMbsLayoutCode, While this is set next-mission functions in TppMission, it gets its actual value in TppMission.Load where unless it’s a story mission is driven by TppMotherBaseManagement.GetMbsTopologyType(), with further setup via TppLocation.ApplyPlatformParamToMbStage

You can derive the layout pack using TppPackList.AddFOBLayout

MB:

local
layoutPack="/Assets/tpp/pack/mission2/"..missionTypeName.."/"..missionCodeName.."/"..missionCodeName..string.format("_ly%03d",vars.mbLayoutCode)..".fpk"

FOB:

local
layoutPath="/Assets/tpp/pack/mission2/"..missionTypeName.."/"..missionCodeName.."/"..missionCodeName..string.format"_area_ly%03d",vars.mbLayoutCode)

..".fpk"

FOB also has clusterLayoutPack:

local
clusterLayoutPack=layoutPath..string.format("_cl%02d",clusterId)..".fpk"

Layouts use the packs /pack/location/mtbs/pack_layout/mtbs_layout_[5 number layoutCode].fpk to define the placement and types of clusters of platforms and bridges surrounding them, and /pack/location/mtbs/pack_area/mtbs_area_ly[layoutCode]_cl[clusterId].fpk to place gimmicks and other entities that can’t be parented to Mother Base layout locators. While it’s not fully known how they work, the game will not accept empty .fpk/.fpkd at those paths when loading a layout.

Idroid/UI .mbl layout files are in /Assets/tpp/pack/mbdvc/mb_dvc_top.fpk

Mother Base layout notes

While positions of all (except command) change between layout 0>1, from 1> BaseDev and Spy(Intel) doesnt move, and from 2>3 Medical and Support dont move

rotations change between 0>1 (all clusters but medical and combat), but no change between 1>3

Game sometimes uses releative positions and rotations to the plnt or cluster center,

which can be gotten via MotherBaseStage.GetDemoCenter and various helpers built around that

If you want to cut down on work you may just want to support just mbLayout 3, which has the following cluster centers

mbLayout 3
