change property of multiple selection

Graphics Shaders & Materials
1

I would like to select multiple objects in the scene and change a common property on all of them.

For example, select many pieces of terrain and change the material they use by selecting a new one in the mesh renderer component from the editor. Currently this will only change the property of the first object I selected. Is there a correct way to do this or is it not supported?

If it’s not supported is there a good example of code that will run through each child object of a game object and change a property, something I can run during the initialization of the level? My searching the forum and wiki hasn’t come up with anything.

Here’s an Editor script that does this…

class AssignMaterial extends ScriptableWizard 
{ 
    var theMaterial : Material; 
    
    function OnWizardUpdate() 
    { 
        helpString = "Select Game Obects"; 
        isValid = (theMaterial != null); 
    } 
    
    function OnWizardCreate() 
    { 
        
       var gos = Selection.gameObjects; 
    
       for (var go in gos) 
       { 
           go.renderer.material = theMaterial; 
       } 
    } 
    
    @MenuItem("Custom/Assign Material", false, 4) 
    static function assignMaterial() 
    { 
        ScriptableWizard.DisplayWizard( 
            "Assign Material", AssignMaterial, "Assign"); 
    } 
}
