Comparative blueprint

Hi,

There is the setup of the tutorial that I followed

And this is mine :

On the first screenshot, I think it is a variable “Materials” but on the video the guy had never create this variable, I don’t know where he gets it.
And on the second screenshot, I tried with a function “get materials” and it’s not working.

(There is the video that I followed : - YouTube . I have the same blueprints everywhere and I understand them)

It is an Array named Material of Variable Type: Material Interface.

He just doesn’t build his Blueprint from scratch so a lot of people seem to be having a hard time following his tutorial as he doesn’t seem to fully explain every single detail. Pay close attention and look at the documentation concerning these nodes and variable types.

Mmh okay, but I can’t see where he creates this variable, on which blueprints? Do you have any idea?

I really need help :-/ I’m stuck, I really don’t know where I need to create this array variable …
