A RedLoader research mod for Sons of the Forest that dumps character data to JSON: skeletons, skinned meshes, bind poses, blendshapes, materials, animators, player races and clothing. It is a data source for building character related mods, not a gameplay mod.

What it collects

For the local player, remote players, the bodies the player can carry, every actor type prefab and every live actor:

Rig: every bone with its parent, local position, rotation and scale
Skinned meshes: mesh name, vertex count, render layer, shadow mode, bone list, bind pose rest position and rotation per bone, blendshape names, materials with shader and texture names
Components: script types on the root, its children, rig bones and animator objects
Animators: controller, avatar, humanoid flag, human bone map, layer names and weights, parameters with hashes, clips with length, loop flag and events, discovered states, current state per layer
Rig families: characters grouped by identical bone sets, with bone name overlap against the player rig
Player only: current race, all 8 race entries with head and arms Addressable GUIDs, every clothing piece with item id, slot, renderable GUID, default and worn flags

Commands

Run these in the in-game console.

Command	What it does
`rigprobe`	Dump the player, remote players, carry bodies, all actor prefabs and live actors, plus all loaded clips and controllers
`rigprobe <filter>`	Same, limited to actor types containing the filter, e.g. `rigprobe female`
`rigscene`	Dump every character in the loaded scenes (posers, cutscene characters, props with skinned meshes), one file per character
`rigwatch [player\|robby\|virginia]`	Log every animator state change on the target while you play
`rigwatch off`	Stop watching and write a summary of every state seen
`rigspawn <Type> [variation]`	Spawn an actor in front of you so its live variant gets dumped, e.g. `rigspawn Virginia`

Output

Written to Sons Of The Forest\UserData\RigProbe\:

characters\index.tsv one line per character with rig family and player bone match
characters\clips.tsv every loaded animation clip, characters\controllers.tsv every loaded animator controller and who uses it
watch\<target>_<time>.log and _states.tsv from rigwatch
characters\rigfamilies.txt characters grouped by shared skeleton
characters\<source>_<name>.json full data per character
scene\ the same layout for rigscene

Addressables catalog

Walking the catalog from inside the game crashes it, so the catalog is decoded offline instead. tools/decode_catalog.py reads SonsOfTheForest_Data\StreamingAssets\aa\catalog.json and writes every key with its asset path, type and provider as TSV. Use it to resolve any AssetReference GUID to its asset.

python tools\decode_catalog.py "C:\Program Files (x86)\Steam\steamapps\common\Sons Of The Forest\SonsOfTheForest_Data\StreamingAssets\aa\catalog.json" data\assets.tsv

Build

Requires the .NET 8 SDK and RedLoader installed in the game folder with its interop assemblies generated.

.\build.ps1 -Install

Reference data

data/ holds a captured dump and data/FINDINGS.md, a summary of the player rig, races, clothing, rig families and female assets. Use it as a starting point before running the mod yourself.
