Roblox Weapon Generator — Create Custom Weapons with AI
Describe any weapon, pick a concept, and get a fully textured 3D model ready to drop into any Roblox game. No modeling skills. No Studio experience needed.
Every great Roblox game needs weapons that look like they belong in the world. Stock Roblox tools feel generic. Custom 3D weapons make your game stand out and give players something to get excited about.
PromptBlox generates weapons as individual mods — each one a real textured 3D model you can drag into any Roblox game in Studio. Your sword doesn't have to look like everyone else's.
How to Generate a Roblox Weapon
Describe your weapon
Type your weapon idea in the PromptBlox chat. Be specific: "glowing purple crystal katana with dark energy swirls" will produce something much more interesting than just "katana."
Pick the concept image
See an AI-generated concept showing the shape, texture, and color of your weapon. This drives the 3D generation.
Get your 3D model
The AI generates a fully textured 3D mesh. Standard mods take about 30 seconds; Deluxe mods have higher mesh quality and more detailed textures.
Drop it into your game
Download the model and import it into Roblox Studio. Place it in your game, add a tool script (or grab one from Toolbox), and your weapon is ready to equip.

Frequently Asked Questions
Does the weapon include attack scripts?
The mod is a 3D model — no attack scripts are bundled. You can add tool behavior by writing a short Luau script or grabbing a free one from the Roblox Toolbox. The hardest part (the model) is done for you.
Can I use generated weapons in any game?
Yes. Generated mods are yours. Drop them into any .rbxlx project in Studio — your maps, games from friends, or any Roblox project you're working on.
What file format does the weapon come in?
Weapon mods are delivered as mesh files importable directly into Roblox Studio. See our add items guide for step-by-step import instructions.
How much does a weapon cost?
Standard weapons are 10 credits. Deluxe (higher detail) are 20 credits. New accounts get 60 signup credits, daily refill credits, and an optional 100-credit Discord bonus after manual review — enough for 8-16 weapons. Pro plans add a starter bonus and included monthly credits that refill over time.
