How to Customize Your Game in Roblox Studio
Your AI-generated game is a starting point, not the finish line. Here's how to make it yours in Roblox Studio.
PromptBlox generates the structure, theming, and gameplay of your game. Roblox Studio is where you fine-tune every detail. Even if you've never used Studio before, these steps will get you customizing in minutes.
Moving, Resizing, and Deleting Parts
Select and move parts
Click any part (block, wall, platform) in the viewport to select it. You'll see colored arrows appear — drag them to move the part along that axis.
- Move tool (Ctrl+1): Drag parts in any direction
- Scale tool (Ctrl+2): Resize parts by dragging handles
- Rotate tool (Ctrl+3): Spin parts around any axis
Press Delete to remove any selected part.
Tip:Hold Ctrlwhile moving to snap parts to the grid. Change grid size in the Model tab under "Move" to get precise alignment.
Changing Colors and Materials
Change colors and materials
Select a part, then open the Propertiespanel (View → Properties if it's not visible).
- BrickColor / Color3: Click to pick any color
- Material: Choose from Plastic, Wood, Metal, Neon, Glass, Grass, and dozens more
- Transparency: Set between 0 (solid) and 1 (invisible)
- Reflectance: Make surfaces shiny (0 to 1)
Tip:The Neon material makes parts glow — great for signs, lava, and sci-fi builds. Combine it with bright colors for maximum effect.
Adding Models from the Toolbox
Browse and insert models
The Toolbox is Roblox's built-in marketplace of free models, plugins, and assets.
- Open View → Toolbox
- Search for what you need: "sword," "car," "NPC," "tree," etc.
- Click a model to insert it into your game
- Position it where you want using the Move tool
Test your changes
Press F5to playtest at any time. You'll spawn as a player and can walk around, jump, and interact with everything. Press Shift+F5 to stop and return to editing.
Test frequently as you make changes — it's the fastest way to catch issues.
Adding Game Passes and Monetization
Set up game passes
Game passes let players pay Robux for perks in your game.
- Publish your game first (see our publishing guide)
- Go to the Creator Dashboard
- Select your game → Monetization → Game Passes
- Create a pass (e.g., "VIP Access," "2x Speed," "Exclusive Skin")
- Add a script to check if the player owns the pass
Tip:Popular game pass ideas: VIP access, speed boosts, exclusive areas, custom trails, extra inventory slots. Start with one pass and add more as players request them.

FAQ
Can I edit the Luau scripts in my generated game?
Yes. PromptBlox generates standard Luau scripts that you can view and modify in Roblox Studio. Look in the Explorer panel under ServerScriptService and StarterPlayerScripts.
Will my customizations survive if I regenerate?
If you download a new .rbxlx from PromptBlox, it's a fresh file. Save your customized version separately in Studio before regenerating. You can also copy specific parts from one file to another.
How do I add sounds and music?
In the Toolbox, search for audio files, or upload your own via the Creator Dashboard. Insert a Sound object into a part or into SoundService for background music.
