Generating a 3D Model from a Text Prompt

The 3D generator turns a text prompt into a textured 3D model you can drop into a game engine. In this guide we'll go from prompt to file.

How it works

In one step, Voidless draws a reference image from your prompt, removes its background, and builds the 3D model from that image. You get a textured GLB (binary glTF), which most engines and 3D tools open directly.

Set the options

• Type: Object for weapons, furniture, loot and props; Character for people and creatures. Characters come out facing forward in a T-pose, as a humanoid or a four-legged animal (Body Type).
• Style and Palette: the same art styles and colour palettes as the image generator, from Low Poly and Cel Shading to Claymation and Photorealistic.
• Mode: draft (15 credits) to try ideas quickly, or high quality (60 credits) for the model you keep, with cleaner textures and lighter files.

Write an object prompt

3D works best for one discrete object: a prop, an item, a character or a set piece. Name it and its defining features: "a treasure chest with iron bands", "a mushroom house with a round door". Choose a style that matches your game; Low Poly gives the lightest, most game-friendly geometry.

Preview from every angle

When it's done, drag the model in the viewer to rotate it. Check the silhouette, proportions and the back, which you can't see in the reference image. Catch problems here before you take it into your engine.

Rig and animate characters

Open a character in the 3D editor to rig it: placing the joints yourself is free, and auto rig costs 140 credits. Once it's rigged, describe a motion such as "walk" or "wave" to animate it for 30 credits.

Use it in your engine

Import the GLB, then check its scale and orientation and set a consistent scale for all your props. If you need another format, the free Mesh to Voxel & 3D Converter turns GLB into OBJ, STL or PLY in your browser. For a blocky look, the same tool turns a model into voxels.

3D or 2D?

3D suits props you'll view from many angles or light dynamically. For a 2D game, the image generator's 3D Render or Low Poly styles give a 3D look on a flat sprite you can animate.
