This free edition is completely free: no limits, no sign-ups, no expiry. It is built to inspect, compare, validate and view your files safely, and it never modifies them.
What it does
- Workspace: load a skeleton (.yft / .yft.xml), inspect it and compare it against another one. Nothing is modified.
- Compare: bone-by-bone comparison between two skeletons (target bone, status and local ratio).
- Advanced diagnostics: a detailed breakdown of the loaded skeleton (structure, bones and internal data).
- Technical report: a clean, readable report of the analyzed file.
- Validator (Doctor): checks the structural health of standalone .ydd, .ytd and .yft files against RAGE format invariants. Read-only.
- Skel Engine: the skeleton recognizer. Identifies the rig, counts its bones and hints at its family (pedestrian, freemode, main character, animal).
- 3D Viewer: view your .ydd / .yft models with their skeleton and textures. Rotate, pan, zoom, front/side/top views, apply/remove texture.
- Textures: a texture explorer with its own decoding engine (no CodeWalker). Open .ytd / .dds / images, zoom and pan each texture, export to PNG.
Requirements
- Windows 10 or 11 (64-bit).
- Portable and self-contained: no installer, no .NET runtime to install. Just unzip and run "TRIUM Skeleton Studio Free.exe".

i, and thank you very much for taking the time to review the tool and for the clear
guidance earlier — I really appreciate it.
I've prepared the **free edition** of TRIUM Skel Studio following exactly what you
pointed out: the listing and the program itself **do not advertise or promote any
paid version**. It's presented simply as what it is — a free tool to inspect,
compare, validate and view GTA V skeletons and models.
A couple of things I thought would be useful for you to know:
- It's a **portable, self-contained `.exe`** — no installer, no runtime to install,
no changes to the user's system. Just unzip and run.
- It is **100% offline**: it makes no network connections at all. Everything happens
on the user's own machine.
You're more than welcome to **inspect it from top to bottom** — run it, poke around
every tab, check its behavior on disk and on the network. I want it to be fully
transparent, and I'm happy to answer anything or make any change you consider
necessary.
Thanks again for your work and for keeping the community in good shape. 🦐
— Jose "Trium"
@reacon good morning my friend
@reacon this is totality free my friend. thanks you! ;)
i hope i can create peds with this, like AI assistant or something, this looks promissing
@William Halverd thank you, that really means a lot! 🙌 For now this free edition is all about reading — inspecting, comparing and validating peds & skeletons, fully safe and non-destructive. I really appreciate the feedback and I'm always working to make it better. Thanks a lot for the kind words! 🤎
@William Halverd Hey William! 🙌 Thanks a lot again for checking out TRIUM — your feedback really means a lot. As a fellow modder I'd genuinely love to connect and chat shop sometime. Your Discord invite seems to be expired and I couldn't find another way to reach you — what's the best channel? No rush at all. Cheers! — Jose "Trium"
Not gonna lie, I don't see a point of this apart from maybe comparing two skeletons with each other, but you can do that manually with just OpenIV and winmerge or something
It kind of reeks of AI slop especially with the whole analysis part, why do you even need the AI to tell you what the gender is based on the skeleton, not to mention that could be entirely wrong because characters like Freemode Male and Female share the same skeleton (so both have breast bones for example), there's a lot of useless information
It feels like a lot but in the end it's whole lot of nothing
I also don't understand the "validating" part, what exactly does it validate?
@HeySlickThatsMe Hey, genuinely thanks for the honest feedback.
First and most important: TRIUM has zero AI — no LLM, nothing. It's a native C# engine that reads the RSC7 binary byte by byte. What you're looking at is just the free read-only tier, and you're right that skeleton-based "gender" is only a rough hint (fair point on Freemode M/F sharing a rig) — it's a convenience label, not the core.
The point of TRIUM isn't comparing skeletons — that's the least of it. The actual engine does things OpenIV + winmerge can't:
• Adapt a YDD onto another ped's skeleton by bone name, no manual reweighting
• Scale a full ped 1.40–2.30m with props staying attached and the rig intact
• Repair broken/deformed skeletons, convert to freemode, and turn a vanilla ped into a full FiveM-ready stream (peds.meta, _resource.lua, etc.)
"Validate" (the Doctor) checks the file is well-formed and won't crash in-game — basically a linter for the resource: structure intact, counts right, safe to load.
Fair that the free/analysis side looks thin — that's intentional, it's the free tier. Happy to show you the real tools in action if you're curious; I'd actually value your eyes on it. 🖤
@HeySlickThatsMe I'm truly glad that someone with your experience, your modding background, and above all your honesty in calling out the fakes of the modding world, has taken the time to share a sincere opinion on my tool.
TRIUM Skel Studio FREE is a completely free version that runs fully offline — everything it does happens internally, through its native engine built around the RSC7 format, which took me countless hours, days and weeks to create. It all runs inside your own computer, which is exactly why it contains no AI of any kind. As you've seen for yourself, it's purely a read-and-analysis version, nothing more.
Out of respect for GTA5-Mods and its rules, I won't give a complete demonstration of the full version here — so if you'd allow me to join your Discord community, I'd gladly show it to you properly. I'd have no problem putting my tool in your hands in its full form, so you can give me your completely honest, sincere feedback — that same honesty that clearly defines you — so I can keep growing, improving and moving forward day by day. By nature I'm someone who never settles; I always strive to give and show the very best of myself.
Warm regards,
Jose "Trium"
where can i get the full version.
@J42Cutta hi, you have buttons at origins and credits... you can push discord for supoort.
