Terms

Last updated 5 September 2026

These are the terms for using Vellum and this site. Using either means you accept them. They are short on purpose — most of what matters is the two sections about what you make and what Vellum copies, and those are worth reading properly.

What Vellum is

Vellum is a desktop tool for building Skyrim Special Edition mods: followers, races, faces, bodies, outfits, quests, dialogue and voice. It reads mods you already have installed and writes a package into a folder you choose.

It is not affiliated with, endorsed by or connected to Bethesda Softworks, Nexus Mods, Mod Organizer, Patreon or ElevenLabs. Every name here belongs to whoever owns it.

The licence

You may use Vellum on the computers you personally use. What you get depends on your Patreon tier:

• Free — and this is most of it. A simple follower, built end to end: her face, her body, her skin, her outfits, the plugin, the FaceGeom, the packaging, the FOMOD installer and the audits. The whole voice side on a plugin that already exists — casting, generating, importing, triage, lip sync. Animations, the dossier, the plugin checks, and the copilot. All of it runs on your own machine.
• From €10 a month. Your own author prefix — without one, everything builds under Vellum, which works and is publishable. And writing structure that speaks: a voiced follower, quests and dialogue, a playable race. And letting an AI agent drive Vellum for you — using the tool by hand never needs a subscription.
• Annual tier. Bringing things in from another game: eyes, accessories, hair, faces, skins.

The line is: Vellum writing something that speaks, or bringing something in from another game, is paid. Everything else is not.

The licence is granted to you. Do not share your sign-in code or your licence file, and do not redistribute the tool, repackage it, or resell it. It is a licence to use Vellum, not ownership of it.

Payment, billing, cancellation and refunds all happen on Patreon and follow Patreon's terms. Cancelling stops future access; it does not undo work you already did. Nothing you built stops working because a licence lapsed.

What you make with it is yours

I claim no ownership and no rights over the mods you build with Vellum. You do not owe me credit, a share, or a mention.

Put them on Nexus Mods, on your own Patreon, on a Discord, or nowhere at all. Give them away or charge for them. A package Vellum writes contains no Vellum code — it is Skyrim records and Skyrim files — so nothing in it carries a licence back to me, and there is nothing for you to credit or comply with.

What still binds you is what always did: the permissions on the pieces you used, and the rules of wherever you publish. Nexus has its own rules about paid content and about assets from other mods; those are between you and Nexus, and this page does not override them.

What Vellum copies, and why that is your responsibility

This is the part that matters most, and it is the part a tool cannot decide for you.

To make a package that works on someone else's computer, Vellum copies files out of the mods you have installed — meshes, textures, morphs, physics files — into the folder it is building. Those files belong to the people who made them. Many modders allow that freely; many require you to ask first; some forbid it outright.

Vellum lists every mod that supplied a file, in the recipe it writes into each package, precisely so you can go and check. Checking is yours to do. Whether you have permission to redistribute a hair, a skin, a body or a set of eyes is between you and its author, and publishing a package built with Vellum is you saying you have that permission.

The same goes for anything you feed it: voice recordings, artwork, presets someone else sculpted. If it is not yours and you have not been given the right to use it, do not put it in a mod.

Voice

If you use the text-to-speech feature, you do so with your own ElevenLabs account and under ElevenLabs' terms — including their rules about whose voice you are allowed to clone. Do not use anybody's voice without their permission. Importing audio you recorded yourself, or that an actor recorded for you, is outside all of this and always has been.

Backups, and no warranty

Vellum writes files. It writes them into the folder you point it at, and it deletes leftovers there from earlier builds so a package does not accumulate rubbish. That means a folder you give it is a folder it manages — point it at a mod folder for the mod it is building, and keep backups of work you care about.

Vellum is provided as is, with no warranty of any kind. I cannot promise it is free of defects, that it will suit any particular purpose, or that a build will always come out right. To the extent the law allows, I am not liable for lost work, lost time, damaged saves, or anything else that follows from using it. If something goes wrong, tell me — I would rather fix it than hide behind this paragraph.

Updates

Vellum checks whether a newer version exists and will tell you when there is one. Because a defect in a tool that writes mod files can quietly damage work, it may require an update before it will keep running: the window is five days after a release, or fourteen if it cannot reach the internet at all. Updates are free at every tier.

If the project ends

Vellum is made by one person. I may stop developing it, stop taking pledges, or shut the licence server down. I will say so on the Vellum page before it happens, and nothing you have already built stops working — a finished mod does not need Vellum, or me, or a server.

There is no promise that the service runs forever, and no refund owed for a future that does not arrive. What you paid for is the months you had.

One promise there is: Vellum asks a server whether it is out of date, and stops if it is too far behind. If I ever shut that server down, I publish a final build with that check removed first, so nobody is left with a tool that switched itself off because I went away.

Fair use of the service

Do not attack the licence server, try to mint licences you were not given, or hand your sign-in code around. Doing so ends your access without a refund.

Changes

These terms can change. The date at the top changes with them, and anything that actually affects you is mentioned on the Vellum page rather than slipped in quietly. Continuing to use the tool after a change means accepting it.

Which law applies

Vellum is made and run from Lagos, Faro, Portugal. These terms are governed by Portuguese law, and disputes belong to the courts of the comarca de Faro.

That last sentence does not take anything away from you. If you are a consumer in the European Union, you keep every protection your own country's law gives you, and you may always bring a case where you live. You can also use the European Commission's online dispute resolution platform.
