[4.13]Landscape master material problem

Hi all,

I have question about landscape master material creation.

First of all, I created 2 material functions for the layer blend and I used a MaterialFunctionCall trying to connect with Parameter in order to use material instance to adjust the settings. However, when I used a master material to create a new master material instance, I can not see all the parameters that I created. At the same time, I made different parameter as a specific group.

The problem is that I can not see all of them.

Are you using the same parameter names in different groups? I don’t believe that works, the names have to be unique.
