[Closed] how to copy modifiers with all data?

Nope, ‘fraid not…

Try out the steps mentioned…

1. Create two boxes side-by-side
2. Apply an Edit Mesh or Edit Poly modifier to the left box
3. Go to the Poly sub-object level, and select one of the sides of the box
4. Bevel the selected face out
5. Exit the sub-object level (optional)
6. Right-click in the modifiers list, and choose Copy
7. Select the right box
8. Right-click in the modifiers list, and choose Paste
   Upon pasting, you should see the same poly on the right box get beveled as well.

Now the only bit to worry about in the code is steps 6 and 8…

-- select the right box manually
deleteModifier $ 1 -- remove the modifier we had pasted manually
rBox = $

-- select the left box manually
lBox = $

-- get the modifier
theMod = lBox.modifiers[1]

-- try applying it to the right box in a number of ways:
-- standard modifier adding
addModifier rBox theMod
-- nope
deleteModifier $ 1
addModifier rBox (copy theMod)
-- nope
deleteModifier $ 1

-- through the modify panel
max modify mode
modPanel.addModToSelection theMod
-- nope
deleteModifier $ 1
modPanel.addModToSelection (copy theMod)
-- nope

-- maybe via replacing the instance (note that the modifier wasn't deleted last)
replaceInstances rBox.modifiers[1] theMod
-- nope
replaceInstances rBox.modifiers[1] (copy theMod)
-- nope

-- And that's where I ran out of fathomable options and tried the uiaccessor stuff

[size=2]The only method I can think of, which is going to be pretty limited as well if there’s multiple modifiers on the object to which you wish to paste the modifier, is to instance replace the object -below- the modifier.

e.g.
[size=1]

newObject = copy lBox
objectToGetTheModifiers = Sphere()
instanceReplace newObject [/size][/size][size=2]objectToGetTheModifiers
delete [/size][size=2][size=1]objectToGetTheModifiers

But as all the modifiers that may pre-exist on [/size][/size][size=2]objectToGetTheModifiers get lost, and you may not be able to re-apply them (due to the very problem we’re trying to solve here), that’s not always going to be a solution.
