How can I put a new layer of paint on uefn?

I’m new to this and it’s probably something very simple, but how can I make my paint appear in the paint layers?
I know how to create them but when I want to put them there, how should I do it? Should I drag it or look in the folder that was saved?

Im not too cluey on making layers, so I could be incorrect or inefficient…

But yeah, create a new layer, then go to the YourProject_sharedassets folder in the Content Browser and double click on the layer to edit it. you can drag the material to it from there.

Theres also another thing, I’m not to sure about either, its the no weight blend thing.
I think the standard paint, grass layer is weight blended and all the others are no weight blended
So when I had to create layers I used weight blend for the main material and no weight blend for the others.

I honestly tried to edit it by double clicking on the new layer but I couldn’t.
I created this new layer

and I want to replace that layer with the default layer that appears when you create a new layer

If I don’t find a solution I’ll have to ask again in the next days haha
