Hi, I want to create a 3d animation triggered by opening and closing hand. I saw a vid did exact same thing I want to do: https://youtu.be/t7LPkvn6Wuk.
But Idk how to set trigger to exported 3d models and assign the animation that was also created in Blender. Can anyone please teach me to do that? Thank you so much! ❤️
