Use Unity asset extraction tools such as AssetStudio, UABEA, or UnityEX
Open the game’s data files, usually in the GameName_Data folder
Load the resources files, sharedassets files, or asset bundles into the tool
Search for model assets with names like Mesh, Model, or FBX-related entries
Export the selected model assets as FBX if the tool supports it
If FBX export is unavailable, export meshes, textures, and materials separately
Rebuild the model in Blender or another 3D tool using the exported assets
For asset bundles, extract the bundle first, then locate the model files inside
Check whether the game uses encryption or custom packing before extraction
Use the correct Unity version support for the extraction tool
Verify the extracted model for missing textures, bones, or animations
Respect copyright and permission requirements before extracting game assets
