Unreal Engine 5 is not just a performance problem, it is a UX problem

Article in wich I explain my point on view on the performance issues often linked to Unreal Engine 5

ShaderGraph Lighting

ShaderGraph Lighting is a github repository which contains a handful of shadergraph subgraphes to recreate a PBR lighting.

All those subgraphes are a rewrite of Unity's URP code to match the same result.

Decal Driven Effect System (DDES)

The decal driven effect system is a "hack" of the unity's render pipeline that we developped for our student project Lost In depiction.

This hack allow us to use the decal buffer as input for other effect like post processing or shaders.

Jack & Flo

Directed by Amaury Campion

Jack, a former lighthouse keeper in his prime, lives isolated on his cliff-island lost in the middle of the ocean. He lives a peaceful existence at the top of the island, surrounded by his house, the lighthouse and a small tree. It seems that Jack is the last human being. While fishing from the top of the cliff, he accidentally encounters a great white pelican stranded on his island. A story of friendship begins between the two, which will profoundly change Jack’s daily life.

In this project I worked on

• Optimisation

• Integration

• VFX

• Meta Quest to Pico port

MOBILE SUIT GUNDAM: Silver Phantom

MOBILE SUIT GUNDAM: Silver Phantom is the first feature-length VR interactive film.

I had multiples roles on this project and created a lot of tools and effects. A few examples:

• Automatic testing and live metrics analysis software.

• Pre-baked animated shadow system.

• Frame perfect 360 recorder (Billboard friendly).

• Custom animations tracks (Video bufferisation, Render settings, Shader parameters

• Custom Meta ASW implementation.

• Unity URP rework and optimisation.

Masters of Light

MASTERS OF LIGHT, an electrifying action adventure game where you harness unstoppable magic superpowers with HAND TRACKING

My role on Masters of Light was to create advanced technical arts effects, and to find a lot of tricks and tricks to achieve the desired visual quality while maintaining a steady 72FPS.

ASTRA

Astra is a mixed-reality documentary about the planets and moons that make up our solar system.

On Astra I developped tools to help the team achieve high graphics quality while keeping the performance under control. For example :

• Metrics analysis tool to understand performance issues.

• Render pipelines features to help with complexe perspective or composition.

Emperor

EMPEROR is an interactive and narrative experience in virtual reality, which invites the user to travel inside the brain of a father, suffering from aphasia.

For this project I created cloth-like VFX simulation and had the responsability to keep the performance at the required level.

Quetzal Islands

Flying game made in one week with a team of seven.

In this project, I was responsible for the creation and development of materials utilized by artists, as well as the design and implementation of lighting and environmental features, such as clouds and water.
