Another thing that can bog down the modeling panels is smooth preview being used on a lot of objects. Also if your scene is getting complex and you don't feel like making display layers for everything then you can use this script I made. It works on components as well as objects. You can put it on a shelf or make a hotkey or whatever. I went the hotkey route. //---------------------------------------------- { //--get panel that has focus. string $currentPanel = `getPanel -wf`; //--if none available, get panel under mouse pointer. if ($currentPanel == "") $currentPanel = `getPanel -up`; //--make sure panel is a modeling panel. string $panelType = `getPanel -to $currentPanel`; //--if so, carry on. if ($panelType == "modelPanel"){ //--query if isolation is active. int $isolateCheck = `isolateSelect -q -state $currentPanel`; //--if its on, turn it off pweez :3. if ($isolateCheck == 1){ isolateSelect -state 0 $currentPanel; //--if not, turn it on. }else{ enableIsolateSelect $currentPanel 1; isoSelectAutoAddNewObjs $currentPanel 1; isolateSelect -state 1 $currentPanel; isolateSelect -update $currentPanel; } } } //--------------------------------------------------------------
