Making material instances by following youtube lessons with blending from rocks to grass. In material preview everything is fine, but when i apply it to landscape horizontal planes are black, only vertical rocks with material.
I haven’t used landscape in a long time, but if I remember correctly, there is some part of the landscape details where you set the blend weights for all the layers in the material you are using. This looks similar to what happens when you don’t set all the weights, so maybe check on that.
