moving vertice, the vertice around selected vertice moving along

[asiaphone12]

I dont know the name of this problem so it’s hard to search around. I was looked at manual but still find nothing. so I hope someone will help me.

I choose a vertice, and I grab it. but the vertice around it moving along selected vertice.

example:

like the pictures above, when I grab the vertice, the other vertice moving along. what the cause of that?

Mirror modifier.

no, not the mirror one, but the vertice that in another edge from selected vertice.

the one that I give red mark (maybe I must do this sooner). it’s moving from it’s place. how to fix it so that it’s not moving again?

The Subsurf modifier affects all the vertices in the mesh. You have set the modifier to be applied in edit mode so if you move one vertex then it will affect the position of connected vertices. Move a vertex in the main object and you’ll see other vertices move as well.

thanks richard, it’s solved. I’m still following tutorial though, and kind of pressing anything I see for experiment, and get freak out when something goes wrong. I hope your help in the future guys.
