Question Random tiling shader texture rotation

I've been working on a Random tiling shader to use it for large fields of grass and don't notice patterns forming.
I mannaged to create a shader that randomly Shapes the "Tiles" but I can't find a way to rotate the tiles randomly. I only mannaged to make the tiles rotate acoording to object position or Absolute world position.

This is the shader graphs net i have created. (I'm an absolute noob).

(The Add node at the and connects to the Basemap texture and the normal texture.)

And this is the result:

 

Check out Ben Cloward's recent videos on this very subject: https://www.youtube.com/c/BenCloward/videos

Episodes 42-48 go over UV tiling, rotation, scale, offset, randomization, pattern breakup etc. In both Unity and Unreal.

 

Thanks a lot!
