Don't forget to add slight jaw movement or throat pulses to make the speech feel weighted and natural. Why Use Built-in Tools Over AI? While AI tools like
While not native to Blender, NVIDIA’s uses deep learning AI to instantly generate rich facial animations from just an audio file. You can export the resulting animation data as an FBX file or shape-key cache and import it directly onto your Blender character mesh for incredibly lifelike results.
