Is there a way to manimulate landscape UV coordinates from BP or C++?

When using the landspace tool in the editor, i would like to override the UV coordinates to adjust relative to the distance between 2 vertex. I try with my landscape material but a material is not changing UV anyway a part small generic operation like scaling…

Basically I want to adjust the UV coord relative to a distance between 2 points, it’s maybe not possible to way I imagine, my texture is tiling, I am not sure it’s possible the way I think…

Anyway I ask, if it’s a stupid idea, just tell me. :slight_smile:

Thank you!
