How to Use the Roblox AI Image Generator
Start with one subject, one setting and a clear visual style.
Step 1
1. Pick Your Starting Point
Choose the forest treehouse, museum puzzle or builder preset. Describe the character or scene you want to make, then select your image ratio. Use portrait for a full-body character and landscape for a wider setting.
Step 2
2. Make the Prompt Yours
Describe the outfit, pose, colors, setting and lighting. Try: blocky explorer in a museum, mint puzzle tiles, dinosaur skeleton, bright daylight. Change one detail at a time to compare directions.
Step 3
3. Generate, Check and Save
Choose an available image model and generate. Check the face, limbs, small details and crop, then refine the prompt or save your preferred result. Add final lettering in your design editor and review the image at its intended display size.
