3D AI Image Generator

Make images that look rendered in 3D: rounded forms, soft studio light, materials you can almost touch. For mascots, product heroes, icon sets and rooms.

What is a 3D AI image generator?

It makes images that look like scenes built and lit in 3D software: smooth forms, named materials, soft light and real shadows. You get a flat image, not a model file. Use it for mascots, product heroes, icons and rooms. On Nano Banana 2.1 an image costs 10 credits. You can start for free.

What makes the look

Form, material, light and ground

Name each one in your prompt. Leave one out and the model picks it for you.

  1. Form

    Simple, rounded shapes with soft bevels on every edge. Characters get big heads and short limbs.

  2. Material

    One named surface per part: matte plastic, glossy vinyl, frosted glass, brushed metal, soft fabric.

  1. Light

    Studio light with a direction: a soft key light from one side, a thin rim light on the far edge.

  2. Ground

    A soft contact shadow under each object and a plain or gradient backdrop, so the shape stands on something.

A chubby 3D sea otter mascot in a red swim cap, smiling and waving one paw, in smooth matte vinyl on a pale aqua backdrop

A 3D mascot for a children's swim school: a round, chubby sea otter in a red swim cap, standing front-facing and waving one paw, with a big friendly smile. Smooth matte vinyl material, like a designer toy, with soft bevels on every edge. A soft key light from the upper left, a thin rim light on the right, a soft contact shadow under its feet. Plain pale aqua backdrop. No text.

Two white wireless earbuds floating above their open glossy charging case, which sits on a round sand-colored stone plinth against a warm grey backdrop, the left side empty

A 3D product render of a pair of white wireless earbuds floating just above their open charging case, which rests on a low round plinth in pale sand. Glossy white plastic, a brushed steel hinge, crisp reflections. A soft key light from the upper right, a thin rim light along the case edge, a soft shadow on the plinth. Warm grey backdrop, with the left half of the frame left empty for a headline. No text, no logos.

Nine glossy 3D app icons in a three by three grid on off-white: a house, calendar, chat bubble, bell, lock, camera, heart, gear and folder in coral, butter yellow, mint and lilac

A set of nine 3D app icons in a 3 by 3 grid on a flat off-white background: a house, a calendar, a chat bubble, a bell, a lock, a camera, a heart, a gear and a folder. Each icon is a chunky rounded shape in soft glossy plastic, colored coral, butter yellow, mint or lilac. All nine at the same size and the same three-quarter angle, lit from the upper left, each with a soft shadow beneath and a wide empty gap around it. No text.

A 3D child's bedroom in golden evening light seen through an open door: a wooden bed with a navy star and moon quilt, a shelf of picture books, a striped play tent with string lights and a toy rocket on a round green rug

A 3D render of a child's bedroom at golden hour, seen from the doorway at eye level: a low wooden bed with a navy quilt dotted with yellow stars, a striped play tent in the corner, a toy rocket on a round green rug, a shelf of picture books. Rounded, simplified furniture in soft matte materials. Warm sun through the window casts long soft shadows across the floor. Slight depth of field, the far wall a little soft.

A stylized 3D girl with curly black hair, big brown eyes and freckles in a mint green astronaut suit, holding a glossy helmet under one arm on a deep blue backdrop

A stylized 3D character portrait of a ten-year-old girl in a mint green astronaut suit, holding her round helmet under one arm. Slightly large head, big brown eyes, freckles, short curly hair. Soft skin shading, matte fabric on the suit, a glossy visor on the helmet. A soft key light from the left, a warm rim light from behind. Plain deep blue backdrop that fades darker at the edges. Full body, standing.

The word SALE in puffy, glossy bubblegum pink balloon letters floating over pale lilac, with small mint and yellow spheres and rings around it

The word "SALE" in thick, puffy 3D letters, inflated like balloons, in glossy bubblegum pink plastic with soft white highlights. The letters float over a pale lilac background, with a few small spheres and rings in mint and yellow drifting around them. Soft studio light from the top, a soft shadow under the letters. No other text.

How to make a 3D render

  1. Shape the object

    Say what it is and how it is simplified: rounded, chunky, soft edges, big head. A mascot faces the camera on a plain backdrop the first time.

  2. Give every part a material and the scene a light

    Name the surface of each part, then where the light comes from and where the shadow falls. These two choices do most of the work.

  3. Reuse it as a reference

    Once a mascot or icon looks right, attach it to the next prompt and say what must stay the same. Nano Banana 2.1 takes up to 14 reference images.
