# 3D Utilities
> Create textured 3D meshes from text prompts or images, then refine geometry and materials for faster ideation and production workflows.
The 3D Objects workspace enables you to convert images and text prompts into fully textured 3D assets that can be downloaded or used directly within Krea. It is designed for artists and creators who want to incorporate 3D into their workflow without the overhead of traditional 3D software.
## Image to 3D
Image to 3D is the recommended starting point if you already have a sketch, render, or product photo.
Example workflow:
1. Click **Add image** in the input card and upload a clear image of the object you want to convert.
2. Select your preferred 3D model in top-left dropdown. (see: available [models](#video-models))
3. Optionally enable PBR if you require more realistic materials and lighting behavior.
4. Click **Generate** and review the 3D preview in the output card.
PBR (Physically Based Rendering) is an optional setting that adds a layer of material realism to your 3D output.
For best results, use images where the main object is clearly separated from the background and well lit.
After generating a 3D object, you have four options below the result: **Retry**, **Reuse parameters**, **Send to Realtime**, and **Download**.
## Downloading 3D files
Once you’ve generated a 3D object and downloaded it, you can use it in a variety of downstream tools and workflows:
* Bring the model into content creation tools (Blender, Maya, Cinema 4D) as OBJ, FBX, or GLB for further modeling, retopology, texturing, or rigging.
* Use GLB directly in web viewers, game engines, or AR frameworks that support glTF/GLB for real‑time rendering with PBR materials.
* Export STL for 3D printing, prototyping, or fabrication via slicer software like PrusaSlicer or Cura.
* Export PLY when you care about dense geometry and vertex colors, for scan cleanup, measurement, or scientific visualization.
## 3D to Realtime
Clicking **Send to Realtime** takes your 3D mesh directly into Krea's Realtime canvas, where you can use it as a compositional reference for image generation. The Realtime model reads the shape and spatial layout of the object and uses it to guide the output, so you can generate fully styled, textured images that match the pose and structure of your 3D asset without having to describe the composition in a prompt.
