global variables in shader graph??

is there any way to create a global variable for shader graph ?
i tried create a custom node and then change te required value via a script but i cant access to output values or input values
thanks and sorry for mi english (google translator edition)

is not very intuitive, but create the property in the blackboard (where you expose parameters) and disable exposed, that will make shader graph to read that value from global variables, hope it helps

This might help :slight_smile:
