Easy Scene
Converts a scene full of separate Static Mesh Actors into instanced ones in a click, and back again if you change your mind. Written as an Editor Utility Widget plus a Python script, so there is nothing to compile.
- Static Mesh Actors to ISM or HISM, and back
- Batch edit of mobility, shadows, collision, navmesh, decals, WPO
- Names the result and drops it into an Outliner folder
- Works with Nanite when converting to ISM

- 60+ native Studio actions, selected automatically
- Real-time building: geometry, UI, terrain, lighting
- Luau generation, refactoring & debugging
- Runs entirely in Studio, no API keys or external tools
Try Genesis

- Natural-language control of the engine

About Me
Oscar LumiereGeneralist Technical Artist · Tessermind
I'm a Generalist Technical Artist building pipelines that make game development faster, prettier, and more efficient.
My journey into gamedev started in the early 2000s with map editors, and it never stopped. Today I specialize in Unreal Engine — from materials and Niagara VFX to Blueprint systems and Python-based tooling. I bridge the gap between art and engineering.
As an Epic Games Authorized Instructor (GOLD), I lead a developer community of 1,000+ members and run workshops for both beginners and seasoned professionals. I've shipped multiple titles on Steam.
// 07
Engine & Language
Side work at a lower level: my own engine and my own language, both written from scratch.
Nyxtale
A visual-novel engine of my own, written from scratch for narrative and story-driven games.
Nyx
A programming language I designed and implemented myself. My own take on syntax, tooling and runtime.

Consulting
A session with your team on Unreal: performance, pipeline, or getting people up to speed.
