Guide
If you have never used an AI 3D generator before, the most useful thing to understand is what the output actually is. You get a mesh — a 3D shape file — that you can open in Blender, Unity, or a viewer. It is a starting point, not a finished product.
The output is a downloadable 3D file, not just an image.
You can start from text, a photo, or a sketch.
Expect a rough first draft, not a polished final asset.
AI 3D generators take an input — either a text description or a reference image — and produce a 3D mesh file. MagicOBJ exports GLB format, which opens in Blender, Unity, Unreal Engine, and most 3D viewers.
The result is a rough shape with approximate surfaces. Think of it like a fast clay sketch. It gives you something to react to, rotate, and evaluate before you decide whether to refine it or try a different direction.
Text prompts work well when your idea is still forming. You describe the object and the AI interprets the description. Image input works better when you already have a visual reference — a photo, sketch, or concept illustration — and want the 3D form to follow it more closely.
Both approaches produce the same type of output. The difference is how much visual guidance the AI starts with.
Good prompts describe shape, materials, and purpose. Instead of writing 'cool robot,' try 'a compact bipedal robot with rounded joints, matte gray armor panels, and a single camera eye.' The more specific the description, the more useful the first pass tends to be.
Mention the object, its shape, and its materials.
Include the intended use if it matters (game prop, print concept, Blender sculpt).
Keep it clear rather than long. Precision beats word count.
Download the GLB file and open it in a 3D viewer or Blender. Rotate it, check the proportions, and decide: is this close enough to refine, or should you adjust the prompt and try again?
Most beginners get the most value from rapid iteration. Generate a few versions, compare them, and invest cleanup time only in the ones that work.
No. You can generate and download models with just a text prompt. But knowing basic Blender helps if you want to clean up or modify the result.
For concept work and rough prototypes, often yes. For polished production assets, you may need to refine the mesh afterward.
Adjust the prompt or try a different input and generate again. Fast iteration is the main workflow.
