For InputChannel, when you have a vector, like Position, there’s 3 buttons… Extract X, Extract Y, Extract Z. Best I can tell, they all do the exact same thing. If nothing is connected, you get a Breakout, which makes sense. If you have another node after it, like say Negate, if you hit Extract Z, the breakout gets added, but with X connected to the Negate.
So either the setup of the Breakout is wrong, or we just need 1 button to convert to float.
