Rezillo Ryker

Rezillo Ryker (alias RezilloArt) is a veteran VRChat Trusted User, 3D artist, animator, and one of the most influential avatar creators in the platform's history. Joining VRChat on February 27, 2018, Ryker is the original creator of The Rexouium — an open species and avatar base that has become arguably the most widely-used furry avatar base on VRChat, often referred to informally as the "default avatar" of the VRChat furry community.

With over 10 years of professional experience in 3D modeling and animation, Ryker operates a Gumroad storefront selling premium avatar bases and has built a distinct community — Rexouria — around the species he created.

VRChat Profile & Background

Rezillo Ryker joined VRChat on February 27, 2018, during a period of rapid platform growth following VRChat's viral surge in January of that year. He holds the 8 Years legacy badge and the Early Supporter badge, indicating he financially backed the VRChat platform when VRC+ first launched — one of the more notable facts given that his current profile shows no active VRC+ subscription, suggesting the badge reflects historical support during the launch window.

His bio establishes clear expectations around social interaction:

"I am an avatar creator and I have worked with 3D over 10 years.

Please don't just send me a friend request, if I don't know who you are then I will ignore the friend request."

The Rexouium

The Rexouium is Rezillo Ryker's most significant creation and one of the most culturally impactful avatar bases in VRChat's history. First released in 2021, it is an open species — meaning other creators are permitted to make their own bases, accessories, and derivatives using the species design.

Name & Lore

The name Rexouium is a portmanteau:

• Rex (Latin) = King
• Ouium = Caretaker (invented)
• Combined meaning: "King Caretakers"

In Ryker's own lore, the Rexouium are a fictional species that serve as the king caretakers of their world. They are described as notably tall — typically reaching 7 feet in height — agile climbers with strong legs built for speed and jumping.

Design & Technical Features

The Rexouium base is distinguished by a highly canine facial structure with significant versatility — its blendshapes and proportions allow it to be adapted into many different animal species beyond its default form:

Feature	Details
Face Tracking	Full VRChat face tracking support (via templates)
Eye Tracking	Native VRChat eye tracking, out-of-the-box
Visemes	Full facial visemes for voice-driven expression
Full Body Tracking	FBT-ready rig
Leg Styles	Digitigrade and plantigrade options (newer versions)
Platform Support	PC and Android (Quest), with separate optimized builds
Blendshapes	Extensive customization sliders for species adaptation
Avatar 3.0	Fully Avatar 3.0 / SDK3 compliant
VRM Support	Compatible with VRM format in addition to VRChat SDK

Community Impact

According to the official VRChat Wiki, the Rexouium base by Rezillo Ryker is commonly regarded as the informal "default avatar" of furries on VRChat — a distinction that reflects the sheer prevalence of the base across the platform. Its canine facial structure, broad customizability, and strong technical foundation led to it becoming a baseline that many avatar creators build accessories and clothing for, further compounding its ubiquity.

The base is noted for being accessible to both beginners (via free public VRChat versions) and experienced creators (via the full purchased Gumroad package with source files), making it one of the most community-accessible premium bases available.

Public Free Versions

Ryker makes several free public versions of the Rexouium available directly in VRChat:

Version	Platform	Notes
Rexouium Digi HD	PC	Digitigrade legs, face tracking pre-setup
Rexouium Legacy	PC	More optimized than HD; older standard version
Rexouium Quest	Quest/Android	Highly optimized fallback, created by community contributor Craziux

Ecosystem & Third-Party Bases

As an open species, the Rexouium has spawned a significant ecosystem of third-party avatar bases:

Base Name	Creator	Notable Features
Rexouium Evolved	Tosca	Digitigrade/plantigrade options; EvoRex HD (2023) adds split UVs for higher-res textures
Rezuium	Hirozu	Alternative style; built-in face tracking; appeared in HTC U24 Pro commercial

The Rezuium's appearance in an HTC commercial is a notable crossover into mainstream hardware advertising — the company initially credited the base creator after community pressure following a breach of the model's terms of service.

Commercial Licensing

The Rexouium uses a tiered licensing structure:

• Standard license — Covers personal use and commissions. Does not require the commercial license.
• Commercial license — Required for physical merchandise (e.g., 3D prints, T-shirts sold to the public) or digital products where the model itself is embedded in a sold product.
• Open species — Others may create bases using the Rexouium design with credit.

Other Works

Beyond the Rexouium, Ryker has produced additional avatar bases sold via Gumroad:

Canis

The Canis avatar (Latin: "dog") is a generalist canine base designed for maximum adaptability. Unlike the Rexouium, which has its own distinct species identity, the Canis is intentionally species-neutral — its customization sliders allow it to represent a wide range of canine and non-canine species.

"This is a general canine avatar I have made that has a lot of customizing sliders and built for in mind for anyone to make about any cute canine species or even other species that one may like to change to. Example: you can create the neck to be more arched/feral and widen the nose and body to fit more like a Hyena."
