Unreal 4 Landscape test

Hey everyone! So this is an Unreal 4 test map I built to prototype out a quick way to create a large traversable landscape and get high fidelity in the landscape material without having to do any hand-painting of material layers. The landscape here is just under 10 sq kilometres, fully traversable. The landscape textures are driven by masks and terrain slope in the shader. I will be looking to develop this further in the future, in between my Star Wars project, and all my other personal projects that I tend to bounce back and forth between. As always, any thoughts / feedback is welcome & appreciated. Thanks everyone!
