Hello, I don't understand why connecting the random value output and any of the grey inputs on the right doesn't match. What do I need to add? Thanks!
The way this seems to normally be done is to drive the Random Value's ID socket with an integer. This changes the Value output socket to output a single value:
One of the not-well-documented features of 3.0 Geometry Nodes is that some nodes output type depends on their inputs. In this case, an 'ordinary' ID would lead to a field output (the diamond shape) but forcing an int into the ID socket changes the output type to a single float value.
