Make it possible the Texture Materials that are already setup like Quixel megascans to be able to just Drag and Drop as a new layer of texture into the paint tab and be able to change nodes if you want something else from there, this is really complicated and a complete mess idk how this is not done yet.
I want to freely be able while I already created a MWLandscape Island for example and now searching on FAB I see a new texture I want to add it to an already landscape that has texture but I want a new one to be added so I can freely paint and that’s pretty much it.
Just like Import new Texture and start Painting the terrain with it.
