[Closed] Difference between Ctrl+E & DragDrop Button

Hi everybody !

Sorry for this basic question, but I have difference between the 3dsmax reaction between Ctrl+E/Shift-Enter and DragDrop Button. :banghead:

Simple Sample here :
Works well with the Ctrl+E (LOD1 = 50% poly count of the source), and with a dragDrop button, LOD1 = 100% poly count of the source.

-- Clone
		obj = $selection[1]
		maxOps.cloneNodes obj cloneType:#copy newNodes:&result	
		objLod1 = result[1]	
		objLod1.name = obj.name + "_LOD1"
		deleteModifier objLod1 1

	 	-- Optimize 50
		addModifier objLod1 (ProOptimizer ())
		objLod1.modifiers[#ProOptimizer].KeepUV = on
		objLod1.modifiers[#ProOptimizer].VertexPercent = 50
		
		select objLod1
		$.modifiers[#ProOptimizer].Calculate = on
			
		-- Skin Wrapp
		addModifier objLod1 (Skin_Wrap());
		addMesh = #();
		addMesh[1] = obj
		objLod1.modifiers[#Skin_Wrap].meshList = addMesh
			
		select objLod1
			
		$.modifiers[#Skin_Wrap].meshDeformOps.convertToSkin off
			
		--maxOps.CollapseNodeTo $ 2 off

Maybe need a local/global variable, or something like that ?
