Quixed Mixed inside of unreal

Texturing is the last thing missing in unreal to be a complete suit and not have to go to others
I am not an artist and I don’t see myself capable of modeling but being able to change the textures of objects already created to adapt the style to my game with all those smart materials is incredible
I just used Mixed to texture an object. I love smart materials, but I really missed not being able to see the object with the lighting, postpro, etc from my game.
I hope you have thought of including mixed inside of Unreal(it is not in the roadmap), and that you do not have to be exporting and importing textures btw including being able to make ID texts
