Blender 2.8 Transform stretch problem Whenever I try to transform any edges, all of the surrounding edges will raise up even if they are not connected.


Does anyone know why this happens and/or know how to turn it off?
Looks like you've got Proportional Editing turned on - you might have accidentally activated it with the hotkey O, or by clicking the small blue circle button just above the timeline, a little to the right of center. You can turn it off by pressing O or clicking the button again. That should restore the behavior you're used to.

That being said, proportional editing can be a really useful tool, so if you're not familiar with it, I'd definitely recommend reading up on it!
