Check the format before downloading a 3D asset

01Match the asset to the job

• Poly Haven offers models, textures and HDRIs under CC0. An HDRI is an image commonly used to light a 3D scene ^[1].
• Icons8's Handy 3D Hands provides hand illustrations in PNG and 3D formats. Its page describes editable source files and shows attribution requirements for free assets ^[2].
• Shapefest provides rendered 3D illustrations. A rendered image is not automatically an editable model ^[3].
• UI8 is a marketplace with categories including 3D assets, mockups and interface kits ^[4]. Check the individual product rather than assuming the whole catalog is free.

02Open one file before collecting a pack

Confirm that your editor supports the supplied format and that the resolution suits the final output. Check the specific license, attribution requirement and permitted use before including an asset in published work.

Keep the download's source and terms with the project. That gives the next person enough context to reuse or replace it. A collection labeled free in an old post can still have conditions or paid options; use the current asset page for the decision.
