How do I re-UV the landscape?

I’ve applied a heightmap to my landscape and something about the UVs seems to have changed. It’s almost like the texture is applied as a projection from the side and not the top like you’d expect. How can I re-project the textures so everything looks normal again?

Hi Phenomonaut,

Do you still see these lines if you switch to a basic material?

If not: I wonder what your original material graph looks like.
