What would be the 'best' way to send a 3D asset for someone to use in Unity?

• A. Export an FBX or OBJ that contains all needed files
• B. Save as a PNG image
• C. Copy the source project files from your 3D software
• D. Export as a WAV audio file

Answer: (A)

Exporting the asset as FBX or OBJ is the best choice because these formats are designed for exchanging 3D data between apps and are directly readable by Unity. They preserve the mesh and UV coordinates, and they reference or include textures in a way that Unity can import and recreate the material setup. FBX, in particular, can also carry animation data if you’re handing off a rigged or animated object, making it a very versatile option. When you export, provide the texture files alongside the model so Unity can link them to the materials correctly.

PNG would flatten the asset into a 2D image, so no geometry or UVs are preserved. Copying source project files from your 3D software isn’t reliable for someone else to use in Unity because it depends on the software and project setup. WAV is an audio format and has no relevance to 3D geometry.
