Roblox Decoration Generator — Create Custom Props with AI

Describe any prop or decoration — ancient stone statue, glowing crystal tree, market stall — and get a fully textured 3D model to drop into your Roblox world.

The difference between a game that feels empty and one that feels like a real world is decorations. Barrels in a dungeon, market stalls in a town, glowing crystals in a mine — these details make players stop and look around instead of just running through.

PromptBlox generates decorations as individual 3D mods. You can also supplement with free props from the Roblox Toolbox and community models — but when you want something specific that matches your game's exact theme, generating it takes 30 seconds and gives you exactly what you described.

Types of Decorations You Can Generate

Trees & plants

Crystal trees, dark twisted trees, neon cacti, giant mushrooms. Any plant style for any world theme.

Statues & monuments

Stone guardian statues, ancient obelisks, hero monuments. Great for zone entrances and key areas.

Furniture & interiors

Wooden tables, sci-fi consoles, tavern chairs, throne seats. Perfect for indoor areas.

Barrels, crates & containers

Combat cover, storage props, loot containers. Also great for decoration in markets and warehouses.

Signs & notices

Town signs, warning boards, direction markers. Add them in Studio and customize the text.

Lights & effects props

Torches, lanterns, glowing crystals, neon signs. Atmospheric decoration that also serves as ambient lighting.

Tip:You don't need to generate everything. The Roblox Toolbox has thousands of free community props. Use PromptBlox for the unique hero decorations — the key statues, the landmark trees, the signs that make your world feel original — and fill the rest with Toolbox assets.

How to Place Decorations in Your Game

Import the model

In Studio, go to the Home tab and use Import → 3D Model to bring your generated decoration into the workspace.

Position and scale

Use the Move, Scale, and Rotate tools to position your prop. Hold Shift while scaling to keep proportions even.

Anchor it

Select the model and check 'Anchored' in Properties so it doesn't fall through the floor when the game runs.

Group and organize

Group related decorations (Ctrl+G) and name the group clearly in the Explorer. Good organization saves you headaches when your world gets complex.

Frequently Asked Questions

Can I use Roblox Toolbox props instead?

Absolutely. The Toolbox is great for standard props. Use PromptBlox for the pieces that need to be unique to your game — the centerpiece statue, the themed trees, the hero decorations that set your world apart.

How much does a decoration cost?

Standard decorations are 10 credits. Deluxe (Pro+ only, more mesh detail) are 20 credits. Your account starts with 100 free credits plus 1 free game per day — enough for several props. See pricing.

Can I resize props to any size?

Yes. All generated models can be scaled freely in Studio. Want a giant statue as a landmark? Scale it up. Want a tiny version of the same prop as tabletop decor? Scale it down.
