PartCrewA Roblox game is code, maps, models, interface, animation, effects and sound, all working together. On a small team one person often covers several of these. Knowing what each role does helps you see what your project is missing and write better job posts.
Scripter (programmer)
Writes the Luau code that makes the game work: game loops, combat, inventories, shops, data saving, leaderboards and the communication between the server and players' devices.
- Good at: Luau, client and server structure, DataStores, RemoteEvents, keeping exploits out.
- Ask for: games or systems they built, and how they protect against exploiters.
- Why it matters: almost every game needs at least one. If you only find one teammate, this is often the one.
Builder
Creates the world in Studio: maps, lobbies, obbies, buildings and terrain. Good builders think about how players move through a space, not just how it looks.
- Good at: layout, scale, lighting, terrain, and keeping part counts low so the game runs well on phones.
- Ask for: screenshots or a showcase place, plus how they keep performance in check.
3D modeler
Makes custom meshes in tools like Blender: weapons, pets, vehicles, props and characters. Modelers give a game its own look instead of free-model parts.
- Good at: low-poly modeling, UV mapping, texturing, and keeping triangle counts reasonable.
- Ask for: a portfolio and whether models come ready to import into Studio.
UI designer
Designs and builds the interface: menus, shops, inventories, HUDs and buttons. On Roblox, UI has to work on small phone screens, tablets, PC and console.
- Good at: layout, readable text, scaling across screen sizes, and a consistent style.
- Ask for: screenshots on both phone and PC sizes, not just mockups.
Animator
Makes character and object animations: attacks, emotes, idles, cutscenes. Good animation makes combat and movement feel responsive.
VFX artist
Creates visual effects with particles, beams and trails: hits, explosions, magic, pickups. VFX is a big part of how "juicy" a game feels.
Sound designer or composer
Picks or makes sound effects and music. Make sure every sound and track is licensed for use in your game.
Tester
Plays the game on purpose to break it, and writes clear bug reports. Testers on different devices catch problems the developers never see.
Project lead (often the game's owner)
Holds the vision, decides priorities, writes tasks, keeps the team on track and handles payment. On most small teams this person also fills one of the roles above.
Which roles do you need first?
It depends on the game, but a common order for a first project is:
- A scripter, because the core gameplay has to work before anything else matters.
- A builder for the main map or lobby.
- A UI designer once the systems exist and need menus.
- Modelers, animators and VFX once the game is fun with placeholder art.
Test the core idea with simple parts first. If it is fun with grey blocks, it will be fun with good art. If it is not, art will not fix it.
How the roles work together
Most delays happen between roles: the UI is done but not connected to the scripts, or the models are the wrong size for the map. Write tasks that name both sides ("UI: shop frame, wired to the purchase script") and agree on naming and folder rules early. On PartCrew you can give each teammate a role in the workspace, so everyone can see who to ask about what.
