STATEMENT

Hi, I’m Grace Li!

I am a Technical Artist (Tools and Pipeline) at Riot Games. I have been the Technical Art lead for Sets 13 and 14 for Teamfight Tactics. Current work includes in-game optimization, developing source art pipelines and tools for artists across and in DCC’s, Houdini node mesh decimation, and finding creative and optimized solutions for artists work in engine.

My love for the intersection of Art and Engineering shines through in my personal projects, from 2D and 3D developments in Unity and Unreal to creating my own game engine in Rust, as well as in my experience as a technical artist at Riot Games, with software engineering at Microsoft, and with my time making immersive reality assets with music artists at Sony Music Columbia Records.

EDUCATION

B.A. in Computer Science from Pomona College (2019-2023)

PIPELINE TOOLS FOR PBR TEXTURING PIPELINE

Python + PyQt + MEL + Substance Painter + Maya

Summer 2023, Tools and Pipeline Technical Artist internship at Riot Games

Developed a Substance Texturing Pipeline for the Physically Based Rendering goals for Teamfight Tactics during my Tools and Pipeline Technical Artist Internship.

First, I designined the pipeline and handling the goals of hand-painted physically based materials.

Then, I designed and implemented five new tools in the softwares Maya, Substance Painter, and Riot’s proprietary game engine that handled:

+ export and import
+ file metadata
+ file handling
+ PBR material set up in proprietary engine (engine not shown, NDA)

to support the new pipeline.

Export tooling in Substance Painter with material creation

Import tooling for Environment asset type in Substance Painter

Import tooling for character asset type in Substance Painter

Export tooling for environment asset type out of Maya

SIMPLE RECURSIVE RAY TRACER

Python + Blender

April 2021 + CS 148 Stanford, self taught from syllabus*

Made simple recursive ray tracer to render separate images using Blinn-Phong lighting model including the reflections, fresnel, and transmission effects as well as taking into consideration aliasing and self-occlusion.

* I took a semester off Spring 2021 to do Computer Graphics and Animation, and found all readings and projects off of a Stanford Computer Graphics course here. I went through the readings and projects myself to self-teach myself the material

no transmission, fresnel, or reflections

MONTE CARLO RAY TRACER

Python + Blender
April 2021 + CS148 Stanford, self taught from syllabus

Implemented a Monte Carlo recursive ray tracer using importance sampling with depth 3 and 16 samples to render images in the Cornell box using area light + 16 samples to do color bleeding, global illumination, and volumetric absorption.

SCENE + SHADER

Web GLSL + Javascript + Blender

Repository here
December 2022, class work

Simple scene, created a final project in WebGLSL for Computer Graphics course while abroad.

+ Blinn-Phong lighting
+ vertex and fragment shaders + Animation and modeling
+ all primitive objects + texturing + normals done
