Pinch/bulge organic shape while keeping edge points

(bulges center, add fuse and facet node, if organic geometry) add group node group name: border uncheck base group check include by edges -> enable check unshared edges add attribute wrangle node group: border VEXpression: f@border = 1; add attribute blur node attributes: border blurring iterations: 40 add point VOP node and dive inside add bind node name: border add fit node (feed bind) destination min: 1 destination max: 0 add parm node name: peak add multiply node (feed fit and parm nodes) add displacement node (feed multiply)
