Finding material parameters within blueprint

So what I am trying to do is create a dynamic material that has texture parameters visible so that as I procedurally generate floors it will replace part of the dynamic material. However I am unable to figure out how to open the parameters from the material within blueprints. I have looked everywhere but have yet to find any reference. I am hoping that maybe someone knows how. I will also post pictures if necessary.

Thanks for taking the time to read and respond.


The picture I just uploaded shows you pretty much all the nodes you need to mess with dynamic material parameters at runtime. You just have to make sure the parameter names match the exposed parameters of your material. Let me know if you have more questions
