I'm trying to manipulate the v4 model using Hexagon but I'm a total newb at this. I need to expand her lower face from about mid-nose down, but I don't know how to get everything to expand outward evenly.
I assume you have brought the model in via the bridge?
Once it is loaded, select in the properties panel, then hit "Symmetry". Wait a while until the symmetry panel turns blue - you should see a perpendicular green frame around the figure, showing that the symmetry plane is in the X- axis. If not, select the X-axis.
Go into vertex select mode and select "soft selection" in the properties panel and select a vert - some verts will turn red. Adjust the strength and smoothness so that the red verts cover the area you want to move - don't select right on the centre line. Now move the vert you have selected and the others will move proportionately.
Hope this explains what you want - if not, ask away:)
I'll give it a shot, might take a while to sort all that out. Had Hexagon for like, a day, and yes I bridged the model from Daz
