Using Custom Nodes in UE4 - Tips & Links

Perhaps the biggest tip of all:

Do all your work in a real text editor, then paste it into the custom node

Otherwise you’ll end up murdering people.


There aren’t enough likes on this forum to truly express how much I agree with this.

Since in a custom node you can’t exactly (easily) input other custom nodes, I found defining your functions in a Struct is something I found pretty useful

        return input;

ExampleStruct f;

return f.ExampleFunc(0);

I found this is the next best thing to just adding though a .USF, and haven’t really seen this documented anywhere
