I no, people people got angry at the spread initially, because it's like, like hipster coting,. But i think itf people know what it is now. So you don't have to, like, think, ago, i need to copy something. It's different if it's an object or if it's a a ray or string, right? You can spear t its. That's what i'm reaching for. Position absolutely exactly.
