I just finished mixing the material of the snow and water ice of the UE4 terrain.
I used textures from megascans and RDT Texture. Use Mix to blend the underlying textures. Finally, it is introduced into UE4, and the material of snow and water ice is mixed in UE4.
Ice texture I made reference to Jonathon Frederick material.
