Hey, hi, I'm John O'Reilly

I'm a tech artist and technical marketer living in Britain. Currently I'm working as an Art Evangelist at Unity Technologies! If you're here to check out my work, have a gander at my Games, Artwork, and Blog Posts. | @John_O_Really


Through game jams and personal projects I have been involved in developing a number of games. I particularly enjoy the challenge and reward of working on a more complete project as part of a team.

As an artist I typically focus on larger projects where I can tackle shaders and FX, as well as of prop and environment art. I am passionate about delivering a unique aesthetic through the combination of many disciplines, including branding, post processing, and texturing. The following videos are short breakdowns of my contributions to some of my projects.

Art That Moves:
Creating Animated Materials with Shader Graph

In this blog post I demonstrate the power of vertex shaders, and how to build them using Unity's Shader Graph tool. In order to demonstrate common shader animations I designed and modelled a tropical island scene. The scene does not use any textures or animation assets; everything you see is colored and animated using Shader Graph. The entire project is free to download for reuse in your own projects.

Hobbies and Interests

In the warmer months I camp at my sailing club to teach cadets and race in local cups. In the evenings I enjoy playing a variety of games, but a particular focus of mine is competitive gaming. I’ve been playing games competitively since 2013; since then I have competed in tournaments for Overwatch, Team Fortress 2, CS:GO, DOTA 2, and Mortal Kombat X. Recently I have been teaching myself music production as a hobby, it’s nice to have a creative outlet beside games art.
Another way I pass the time is by helping cultivate communities online, in my free time I moderate the Path of Exile subreddit: a forum with 134,000+ users. Through the subreddit I also created and moderate the /r/PathofExile Discord server, which currently has 40,000+ users. | @John_O_Really
