cant snap a group of vertecies at once.

In Face snapping, be sure to have Project individual turned on:

Does this work differently in Blender 4.1? Snapping worked fine before but now with those larger patches. Snapping seems to work differently. With multiple vertices selected it will move them as a block and not snap them individually. The “Project Individual Elements” is missing. There is an option “Snap Individual Elements To” but it’s not a check box but it toggles it off. I can shift-click on the option that selects both “Face” and “Face Project” but it doesn’t seem to fix it. There is a checkbox: “Project Individual Elements” in the move box in the bottom left corner, but that only appears after the action, checking it doesn’t seem to alter the move.

Perhaps the biggest change in a while is the “Retopology” check box:

But that is more of a convenience for the view so you don’t have to juggle around a thousand options like before. After that the “Face Project” turned on should be enough for all your individual vertices to snap the the target object. You have to be careful since it’s dependent on the viewing angle you are snapping things from.
