for obj in geometry do
(
addmodifier obj (normalModifier())
obj.modifiers[#Normal].flip = true
)

It would't :)
Set selection filter in Main Toolbar to Geometry,
select all objects, add a Normal modifier on top of them all, check a checkbox. The script does the same.
(Not that I am against scripting or something... :))

Just for the fun of it, the script could be written in a single line without a loop as

addModifier geometry (normalModifier flip:true)


AddModifier is mappable, geometry is a collection that can be mapped to, and the normal modifier can be applied as instance to all objects with the parameter flip already set to true.

Sorry, I know, I am a smartA** ;)

well that is another way to do it

Sorry, I hope I did not offend you. (if it did, please accept my public apology!)

I have to admit that if I would have to answer the question, I would have supplied the code you did. But then, when you see someone's code, you start thinking - hmmm, is it possible to get this code shorter? Faster? Does it need a loop? Does it need a unique modifier on each object? Is addModifier mappable? Do I have to explicitly convert geometry to array of does it map directly to it?

So to be honest, I spent some minutes playing with the code and actually LEARNED lots of things myself. Then I posted so other people can learn what I learned.

Once again, sorry if I sounded like "Know It All", I wasn't my intention to sound like I know better...

Peace! :beer:
