Settting a Variable in Material Blueprint

Hi guys,

Have a nice material setup but I want to put in some constants/variables to allow me to affect my material based on gradient, height and position - I have my blueprint setup but I cant get an option to add a variable like you can in normal blueprints.

Everything else works fine but I can’t add the variable.

Check out this section: Creating and Using Material Instances | Unreal Engine Documentation

You basically need to convert those constants and vectors into parameters by right clicking on them. Then you can manipulate them in material instances or blueprints.


was checking with a friend and turned out to be a weird engine bug. I was able to add parameters again after rebuilding the engine from source.
