Heightmap material stretches textures on high slope

I cannot figure out how to force the landscape material to repeat a texture instead of clamping it. My problem occurs on cliffs and sections of mountains where the slope is high. My rock texture gets stretched across the length of the polygon instead of tiling.

Here is my current Blueprint for the material:

Hi Demonicated,
I have the same issue. Did you found a solution?

Try giving the rock texture a separate (smaller) LandscapeCoordinates value. Then it should tile instead of stretch. Sorry for the late answer – I just found this post.
