How to parametrize a landscape paint layer inside a blueprint?
I've been playing around with making tools for editing landscape using blueprints, and I stumbled upon a problem that is rather annoying. The problem is that I can't figure out how to parametrize a landscape layer info. The info is used by an "Editor apply spline" function that modifies the landscape. There should be a way to at least specify the wanted layer by typing it as a string (similar to in the procedural foliage tool where you type in the layer name), otherwise I have to hardcode the layer or make some gigantic if else chain.
Edit: To add, the "promote to variable" button is greyed out.
