I have watch several tutorial that say when using loop cut by using Ctrl + R, we can increase and decrease the number of loop cut by using scroll wheel up and down, but when I scroll, nothing happens.
This picture is when using the loop cut
And this picture is after pressing Ctrl + R. I can only choose where to cut by moving the mouse up and down. No matter how much i scroll, it just doesn't have any effect. Is there any solution?
