I am doing this tutorial. At about 12:00 min CGGeek selects a face and first separates that face with P and then corrects and hits Y to split the face.
I am not familiar with this Y command and don't really understand what he does and why he does this. I understand that this command copies the face and also deletes the original face ? But the face remains part of the original mesh, is that correct ? But why does he do this ?
And I believe after that he deletes the original face
