I created layer material and I want to change the parameters of each layer in blueprint.I use the set vector/scalar parameter value node . But it only can change the parameters in the master mateial by input the parameter name .Is there any way to set the parameters in each layer ?

Use `Set Vector Parameter Value by Info` and `Set Scale Parameter Value by Info` in your blueprint.
