AccuRIG for PC: How to Download & Install on Windows

Introduction

If you have a static 3D character and want to animate it, but rigging a skeleton by hand would take hours, AccuRIG is the free tool that does it in minutes. It is a free desktop auto-rigging tool from Reallusion, the company behind Character Creator and iClone, and it generates a full-body rig with finger rigs for a humanoid character in a guided five-step process, then exports the rigged character in FBX or USD format for Unity, Unreal, Blender, Maya and other tools. There is no payment for the rigging tool itself, and the download from the official Reallusion site is the complete free app.

This guide explains what AccuRIG is, what it can and cannot do, what your PC needs to run it, and how to download and install it from the official website only. You will also get a first-use walkthrough that takes you from installation to a working result in a few minutes. By the end, you should be able to install AccuRIG on Windows and use it in a real project.

AccuRIG is best for rigging game characters fast, adding finger rigs, and preparing characters for engines. Because it is free and legitimate, you do not need a cracked copy or an unknown download site. The official website provides the installer, and the free version is a real, permanent tool, not a short trial.

What Is AccuRIG?

AccuRIG is a free auto-rigging program that you install on your PC for preparing 3D characters. In simple terms, it is a program where you import a static humanoid mesh in FBX or OBJ format, in an A-pose, T-pose or even an irregular scan pose, place a few joint guides on the body, and AccuRIG builds the skeleton and skin weights for you in one guided pass, including a 19-joint body rig and a separate finger rig. You can then browse stock animations from Reallusion’s ActorCore library inside AccuRIG, retarget one to your character, and export the rigged character with its animation.

What makes AccuRIG useful is its speed and its exports. It handles low to high density meshes, it accepts scan poses with axis correction, and it exports rigged characters in FBX and USD for Unreal, Unity, Blender, Maya, Cinema 4D, MotionBuilder and 3ds Max, with presets for each target. The current version is v2.1.0. Three honest notes: it is a Windows-only desktop app, you need to register for a free Reallusion ActorCore account to export a rigged character, and the free version rigs one mesh at a time with no skin-weight editing or mesh reduction, while facial rigging and other advanced tools live in the paid Character Creator workflow. Most ActorCore animation packs are paid, although a small number are free.

System Requirements

These are practical, modern Windows guidelines, not a word-for-word copy of an official specification table. The most important point is simple: AccuRIG is designed for normal Windows PCs, and a modest modern computer is enough to start.

How to Download AccuRIG (Official Method)

The only safe place to download AccuRIG is the official website. Do not download it from random file mirrors or "free download" portals, because those copies may be outdated or bundled with unwanted software. The official site is the source of truth for the current version.

Official download link: https://www.reallusion.com/auto-rig/accurig/

On the official Reallusion AccuRIG page, download the AccuRIG web installer to your Downloads folder. The installer is free, and there is no payment step. You will need a free Reallusion ActorCore account to export a rigged character, which you can create during setup. If a site asks you to pay for AccuRIG itself, or offers a cracked version of it, leave that site and return to the official Reallusion page.

Step-by-Step Installation

Follow these steps in order. Take your time with the install location and component choices, because those are the steps that most often cause problems later.

Download the web installer from the official site — Open https://www.reallusion.com/auto-rig/accurig/ in your browser and download the AccuRIG web installer for Windows.
Run the web installer — Double-click the downloaded installer file and follow the on-screen prompts. It downloads the program files during setup.
Create a free ActorCore account — Create a free Reallusion ActorCore account, or sign in if you already have one. The account itself is free.
Sign in to AccuRIG — Sign in to AccuRIG with your ActorCore account, which is needed to export rigged characters.

Import a test character — Import a humanoid character in FBX or OBJ format and confirm it appears in the viewport.
Check the joint guides — Look at the joint guides AccuRIG places on the character, and confirm you can adjust them.

Tip: You need a free Reallusion ActorCore account to export a rigged character, even if you only export locally, so create the account before you start a real project. The free version rigs one mesh at a time, with no skin-weight editing, so check the free-versus-paid comparison table on the official page before you plan a big job.

Is AccuRIG Free?

AccuRIG is a free download from Reallusion, with no paid tier for the rigging tool itself. You download it from the official Reallusion site, install it, and use it without paying and without a time limit. Be aware of three honest limits: it is Windows-only, you need a free ActorCore account to export, and the free version rigs one mesh at a time with no skin-weight editing, while facial rigging and other advanced tools live in the paid Character Creator workflow. Most ActorCore animation packs are paid, although a small number are free.

That free status is important for this guide. All the steps here use the official download only, and they do not involve cracks, activators or licence keys. If you ever see a site offering a paid or cracked version of the free program, treat it as unsafe and return to the official site.

Frequently Asked Questions

The free version described in this guide is not a short trial. It stays usable after installation. There is no paid tier for the AccuRIG rigging tool itself, but most ActorCore animation packs are paid.
