Your rendering backend is our playground. Rendering and engine programming services

Split-E is the studio of Shady El Mously, a rendering and engine programmer with two decades of shipped AAA work on PS5, Xbox, Switch, PC and mobile: Vulkan, DirectX 12, Metal and proprietary engines, from pipeline design to GPU optimization to cross-platform porting. You work with him directly.

Shipped & trusted across AAA and middleware

What we do

Close-to-the-metal work, end‑to‑end.

We slot into your engine as senior contractors with no ramp-up and no hand-holding, and own the hard rendering and engine problems most teams would rather not.

Rendering pipeline design

Forward, deferred and clustered pipelines: lighting, shadows, particles and post, architected around your art direction and your frame budget.

GPU profiling & optimization

Frame analysis with PIX, RenderDoc, GPAD and Razor. We find the stalls, the overdraw and the bandwidth walls, and we fix them.

Cross-platform porting

Ship one renderer on PC, PS5, Xbox Series, Switch and mobile. Clean backend abstraction across Vulkan, DirectX 12 and Metal.

Shader systems & resource binding

Modern shader pipelines and SRT / resource-binding infrastructure, including a reflection-free binding system shipped in a cross-platform rendering framework.

Engine & framework integration

Deep work in Unreal 4/5, Godot, proprietary engines and cross-platform rendering frameworks. We adapt to your codebase, not the other way around.

Realtime 3D & game development

Beyond games: realtime 3D apps, data visualization and SDK rendering (think SciChart's 2D/3D charts), plus full game development.

Cross-platform Rendering Framework

Designed and implemented a unified Shader Resource Table (SRT) that eliminates runtime reflection, plus a new resource-binding system and dynamic-rendering support across Vulkan, Metal and Direct3D 12, for a commercial cross-platform rendering framework.

What clients say

Unedited feedback from contract clients. Names withheld.

“Shady brings a whole ton of expertise in complicated engineering topics. Great understanding of shader pipelines and a very in depth knowledge of game systems. Asks the right questions, works efficiently, and communicates really well.”
Client, graphics system for a game UI framework
“Working with Shady has been an excellent experience. He is a highly skilled programmer who consistently delivers clean, efficient, and well-structured code. Beyond his technical ability, he is very professional, communicates clearly, and understands requirements quickly, which makes collaboration smooth and productive.”
Client, DirectX rendering fix

Engine technology

SETech: our in‑house engine.

SETech is Split-E's from-scratch multiplatform C++ engine: our own rendering, reflection, scene, animation, physics, audio and editor stack, shaped by two decades of production rendering work. One codebase runs across six platforms and five graphics APIs, and the demos below are that same engine compiled to WebAssembly, rendering through your browser's native WebGPU.

Rendering pipelines

Forward · Deferred · Visibility buffer (GPU-driven) · Ray tracing (DXR)

Composable rendering pipelines

Pass-based pipelines built per app: forward, deferred, a GPU-driven visibility buffer with bindless shading, and DXR ray tracing, with HDR + ACES, clustered PBR, cascaded shadows, SSAO, MSAA and FXAA.

GPU simulation & particles

Compute XPBD and VBD solvers for cloth, ropes, soft bodies and fluids, including Offset Geometric Contact from SIGGRAPH 2025, a strand hair solver on the same framework, plus a fully GPU-driven particle system fed by indirect draws.

Streaming open worlds

Quadtree CDLOD terrain with sector streaming. Worlds can also stream live from OpenStreetMap: real roads, buildings and elevation around any GPS point, no cook step.

Animation with physics feedback

Layered clip blending, root motion and data-driven character locomotion, closed-loop with an active-ragdoll physics animator: hits deflect limbs and ripple through the skeleton before the pose recovers.

Reflection-driven everything

One reflection system powers the scene format, the editor's property panels, XML/JSON serialization and AngelScript bindings. Entities carry script behaviors that hot reload from disk, with no glue code.

Tools, pipeline & AI

The SETechStudio editor, deterministic asset cooking (FBX, Collada, USD), one-command deploys to every platform, and an AI bridge that lets LLM agents author and drive live scenes as JSON.

World Alone New

Drop into your own street. The world is built live from OpenStreetMap around any GPS point you give it (real roads, real building footprints, real elevation) with no cook step and nothing pre-authored. Walk it in third person, read the street names off the sign blades and the building names off their walls.

Strand Hair New

Every hair is simulated. Guide strands run on a GPU strand solver (follow-the-leader length constraints, TressFX-style shape memory, wind and collision), then fan out into tens of thousands of rendered fibres shaded with a Marschner R / TT / TRT model and an approximate deep shadow for self-shadowing. Change the style, the colour, the physics and the beard live, or push the head under water and watch the hair soak, clump and drip dry.

About Split-E

Two decades, close to the metal.

Split-E is led by Shady El Mously, a graphics and engine programmer who has spent two decades in the rendering trenches of AAA and indie studios across Australia, New Zealand, Germany and Egypt.

He's shipped titles for publishers including Rockstar Games, Activision, THQ Nordic and Atari, from L.A. Noire to modern VR, alongside framework-level contributions to commercial rendering middleware. The through-line is the same: deep, low-level graphics code that ships on real hardware. As a former technical director and lead, he bridges engineering, art and design, and plugs into your team as a senior contractor who needs no ramp-up.
