Can you explain a bit more on how to use it? Do I use the .cpp-file? Why does it start with return 1;}? Where do I put it, and how do I reference it in blueprint? I see you say “the ‘plug’ pin”, but how do I instantiate/reference/find that asian thing?
Is the blueprint a Material, and what is the “Custom”-node? And what are the inputs/output type for the Custom-node?
