Custom terrain material error in HDRP

Hi guys,

I'm trying to build a custom terrain shader with the HDRP shader graph, but the material is only compatible with terrain versions below 2018.3.

Any higher than that and the terrain resembles what happens to the unity tress when you turn up your wind settings too high.

Does this have anything to do with that tangent geometry the terrain alway complains about nearly every other material you plug in? If and if not how can I get around it in shader graph? And can I use render textures to update height maps?
