Multiple brushes and func_detail?

I have always thought that converting multiple brushes in a group and then tieing it to a func_detial makes the size a little less… But is that true?

It’s probably “that much less” in the sense of “not noticable at all” - you can always click on the small button saying “ig” in the top bar to edit any brush of a grouped func_detail anyway, so it doesn’t matter either way.

So it doesn’t cut down on size of the map? Like memory wise?

It’s not noticable which is why noone cares.

I merely group brushes into Func_details to make it easier to copy them as required.
