Lead Game Developer — Unity · C# · GPU & Global Illumination, since 2018. I build the experimental thing nobody else dares to make. The blade behind this text is being path-traced and denoised live — the same craft I ship as NovaBake.

02 NovaBake, explained by the render

The bake is the forge.

Scroll drives an incandescent wavefront up the blade. Below the line, the scene is fully converged — real global illumination, warm bounce off the walls, an IES cone across the steel. Above it, raw Monte-Carlo grain. Baking a lightmap and forging a blade are the same motion. Each stage below commits to DONE as the wavefront passes it.

Direct Light + NEE

Next-event estimation samples the area light every bounce — cheap, low-variance direct lighting that converges fast.

PENDING

First Bounce

Cosine-weighted diffuse rays leave the surface and gather the first ring of indirect radiance.

PENDING

Indirect GI

Warm color bleeds off the studio walls onto the blade — one to four bounces of physically grounded global illumination.

PENDING

NLM Denoise

An edge-aware à-trous wavelet pass wipes grain while preserving the specular streak — clean lightmaps at low sample counts.

PENDING

IES Profiles

A real luminaire falloff LUT shapes the key light, so a visible cone lands on the steel like a real fixture.

PENDING

Final · Tonemap

HDR radiance through ACES with a subtle rim bloom. The lightmap is baked — progressive, and cancellable at any sample.

PENDING

Grab the light in the hero (drag anywhere in the top screen) or tilt your device — the whole frame honestly re-converges from sample 0, exactly like a real path tracer. Or hit BAKE in the inspector; CANCEL freezes it at the current sample.

NovaBake — GPU Lightmap Baker

Path-traced global illumination on any GPU — no CUDA, no OptiX, no external baker. Just Unity Compute Shaders. The closest well-known tool needs an NVIDIA card and Windows; NovaBake bakes cross-vendor with zero external executables.

Fully GPU-accelerated baking written entirely in Unity Compute Shaders — runs on AMD, NVIDIA and Intel.
Path-traced global illumination with a BVH-accelerated ray tracer for physically grounded bounce lighting.
Built-in NLM (Non-Local Means) denoiser — clean lightmaps at lower sample counts.
IES light-profile support for real-world luminaire falloff, plus ambient occlusion baking.
Progressive & fully cancellable — preview as it converges, cancel any time without losing the editor.

RAW TRACE NLM DENOISED

This is the live hero buffer — left half is the raw Monte-Carlo trace, right half is the à-trous denoiser output. Drag the light to re-bake and watch the split widen at low samples.

Law of the Sword

"Step into a fantasy world balanced by the spirits of swords and protected by law." A story-rich, cinematic beat 'em up — architected and built solo in Unity, and lit end-to-end with NovaBake. Real production dogfooding of the flagship tool.

Fluid spectacle-fighter combat — time your defend, dodge and attack to build combos and craft your own strategy.
Hand-painted stylized art, cinematic camera work and integrated sound design.
Story told through animated scenes and NPC dialogue you can dig into for lore.
5 episodes, 2 boss fights, 4 mob encounters, 8 Steam achievements — with a roadmap for weapon masteries and story branching.
Lit entirely with NovaBake — the same GPU baker on the Asset Store, proven in a shipped pipeline.

06 About

The experimental thing nobody else dares to make.

I'm a Lead Game Developer working with Unity and C# since 2018. My core is software architecture — robust project structures, single- and multi-threaded systems, ECS/DOTS pipelines, the Unity Job System, and the algorithms that keep real-time projects fast and maintainable.

Beyond engineering I lead teams and run projects end to end, from technical planning to shipping. But what I actually chase is the risky asset — HLSL and compute shaders, real-time global illumination, GPU baking, editor tooling: the unusual, spectacular thing most studios consider too hard to attempt.

Two shipped artifacts back that up: NovaBake, a cross-vendor GPU lightmap baker with no external dependencies, and Law of the Sword, a solo cinematic beat 'em up I lit with my own baker. The tool and the game prove each other.
