Frequently Asked Questions

What does "CC0" or "Public Domain" mean?

CC0 (Creative Commons Zero) means the creator has waived all copyright rights to the content. You can copy, modify, distribute, and use these assets commercially without permission or attribution—though attribution is always appreciated!

How do I use an HDRI file in Blender?

1. In Blender, go to World Properties panel
2. Set Surface to "Background"
3. Click the yellow dot next to Color → Environment Texture
4. Open your HDRI file (.hdr or .exr format)
5. Switch to Rendered view to see the lighting and reflections

What's the difference between a background and a 3D scene?

A background is typically a 2D image or 360° HDRI that provides lighting and a backdrop. A 3D scene is a complete environment composed of actual 3D geometry and assets that you can navigate around in 3D space.

Can I use these free assets with models created by Tripo AI?

Absolutely! Tripo AI's AI 3D model generator creates assets that are compatible with all standard 3D workflows. The models export in industry-standard formats that work seamlessly with these free environments and backgrounds.

Conclusion: From Generation to Presentation

The journey from concept to impressive 3D presentation has never been more accessible. Start by generating your hero asset with Tripo AI's powerful AI 3D model generator, then place it in a free HDRI environment or 3D scene to instantly elevate your presentation.

This combination of image to 3D technology with free, high-quality environments democratizes 3D creation—allowing anyone to produce professional results without the traditional barriers of technical skill, time, or budget.
