I'm trying to follow a video tutorial to learn how to modelling a character in blender. I've reach the point where he explains how to use the proportional editing. I'm tryng to do what he says,but this feature is not working at the same wat as it works on the tutorial and I don't know why. These are the steps I do :

1. I activate the proportional editing by pressing o
2. I select a vertex
3. I press G

what I see is not the movements of a lot of vertex together,but of the whole object. Please check the picture attached where you will see that I've tried to move a vertex with the G key and you see what's happened...thanks.
