Hi ! 👋
I'm Froyok / Léna Piquet, and I'm a Principal Product Manager working on Substance Painter at Adobe since 2014.
In my spare time I used to play with the Unreal Engine, but now I work on own game engine called Ombre.
I also experiment with shaders and sometimes draw stuff.

The recap of my third year of development on Ombre is finally available:

OMBRE Dev-Blog Year 3 | Froyok - Léna Piquet
It's November, which means it is time for another year long recap of the development of my own game engine. I'm a bit late compared to the anniversary date (November 5), but this year has been hectic ...

Marcin Zalewski informed me that his blog post on real-time hair rendering using ray tracing is now available:
mmzala.github.io/blog/hair-ge...
This is nice work, in which he compares NVidia's hardware accelerated hair to several alternatives, including Reshetov's Phantom Ray Hair Intersector.

I had the pleasure of working with [REDACTED] on these 12 portraits over the last few months of 2025, and it was a fantastic technical and artistic challenge.
I have permission to talk about some of the technical process, so I'll post a bit about that below!

I have been running Kubuntu at work for a few months now (I'm on Manjaro at home).
Since I installed this machine my audio levels have been quite low (sometimes roughly at 50% despite the system reporting 100%).
Finally fixed it today, I can blast my ears and ignore my colleagues again ! 😄

I was busy this morning : I changed my brown switches into red one !
They were annoying to remove, but it was worth it.

Have you ever wondered how time is spent in game development? I've made a handy pie chart to illustrate it.

I made a directional noise type I call Phacelle Noise which is pretty fast!
Is it new or does something functionally identical already exist? I'm not sure! But I didn't come across one like this yet anyway, so here's my findings:

Haha, I ditched the pure software renderer a while back due to inconsistent fps on different architectures. It's mostly a hybrid approach with some fx being done in software on top of hardware/GPU renderer.
