Landscape Painting(I NEED HELP)

Hello everyone. I need help in trying to figure this out I cant paint my Landscape because I don’t know how to choose the target layer. I really want to paint my terrain. and I cant. Right now its just a Grass texture and I want to add in like a gravel walk way texture and I don’t know how to paint the terrain HELP ME PLEASE!!!, I’m using Unreal Engine 4.13.0

It’s not really clear on the exact problem you’re having, but I’m going to assume it’s because you have no layer info, there should be a dropdown box on your Paints, just select “Weight-Blended Layer”
