I have followed the steps to connect a character I’ve downloaded from Mixamo to the Mixamo joint rig. (I’ve followed the ‘Enhanced Character Animation with Mixamo in Cinema 4D R21’. Link here : https://www.schoolofmotion.com/blog/enhanced-character-animation-mixamo-cinema-4d-r21

However, when I try to transfer weights to the joints to the Mixamo Control Rig by dropping the character mesh into the Weight Tags field, I cannot do this, and a stop sign shows on my mouse cursor. Can you help me with this?
