I build gameplay systems and multiplayer functionality in Unreal Engine 5 using Blueprints and C++, turning design ideas into working systems.
Services:
- Multiplayer setup (replication, RPCs, client server)
- Gameplay mechanics (inventory, combat, movement)
- Blueprint scripting and refactoring
- Matchmaking, session/lobby systems
- Save systems, UI/HUD logic, AI behavior trees
- Debugging existing Blueprint/multiplayer projects
I work inside your project, follow your architecture, and hand off documented systems.
Game Developement certificate. Background spans 3D art and UE5 build.
FAQ
Which game engines do you build modular kits for?
Unreal Engine 5 and Unity. The Starter and Pro kits are set up for one engine of your choice. The Full Environment Kit is set up for both, so you can use the same kit in either engine.
What pieces come in a modular building kit?
Walls, floors, ceilings, corners, doors, windows, stairs, roofs and trim pieces, all designed to connect. Bigger packages add matching props. Tell me the pieces you need and I will scope them.
Can you match my art style or work from concept art?
Yes. I build stylized, low poly and realistic kits. Send concept art, screenshots or reference images of your game and I will match the look, proportions and color palette.
Do you support Unity URP and HDRP?
Yes. Tell me your Unity render pipeline (URP, HDRP or Built-in) and version before ordering, and I will set up the materials to match so the kit looks right when you import it.
What files will I receive?
FBX meshes and textures, plus engine-ready assets for UE5 or Unity. The Pro and Full kits also include a sample scene showing the kit assembled, so you can see how the pieces fit together.
Will the pieces snap together without gaps?
Yes. Every piece is built on a consistent grid with clean pivots and scale. Send your grid size if you have one, or I will use a standard grid that works well in both engines.
Do you include LODs and collision?
The Pro and Full kits include LODs and collision. The Full kit also adds lightmap UVs. The Starter kit delivers game-ready meshes and textures, and LODs can be added as an extra.
Can you optimize the kit for mobile or low-end PCs?
Yes. Tell me your target platform (mobile, PC or console) and I will set polygon counts, texture sizes and material complexity to fit your performance budget.
Should I message you before I place an order?
Yes, please. Send your references, game genre, engine and the pieces you need. I will confirm the scope, suggest the best package and quote any custom requirements before you order.
Do I get commercial rights to the finished kit?
Yes. You receive full commercial usage rights to the kit made for you, for use in your game or product. I do not resell custom kits made for you.
