Thanks alot for this course. coming from unity 3d background and wow unreal just blows my mind 
i think i will stick now with unreal 5, it is just awesome!
are there any courses for physical masked materials ? i looked in the search but nothing shows up. i made my landscape material with it and it really works out, but is there a way to add it no a normal material to have different physical materials assigned with it ? (like dirt, stone, sand,…)
cheers
