Deforming custom mesh based on body mesh

A system comprising:

• a processor of a client device;
• and
• a memory component having instructions stored thereon that, when executed by the processor, cause the processor to perform operations comprising:
• receiving a video that includes a depiction of a real-world object;
• generating a three-dimensional (3D) body mesh associated with the real-world object that tracks movement of the real-world object across frames of the video;
• obtaining an external mesh associated with an augmented reality (AR) element;
• automatically establishing a correspondence between the 3D body mesh associated with the real-world object and the external mesh;
• deforming the external mesh based on movement of the real-world object and the established correspondence with the 3D body mesh;
• and
• modifying the video to include a display of the AR element based on the deformed external mesh.
