For anyone trying the procedural approach posted by crow87, you need to use screen coordinates for the noise node’s position input. By default the noise is based on world position coordinates which is why it’s aligned to the geometry instead of the screen.

Thanks for answering these guys. I’ve been working a 100 hour week at work, so haven’t had time to even move back to my old workstation, let alone open up an old test project.

being said, I’d suggest not to use ddx/ddy for generating the normals due to the poor blocky results.

It does cause some hideous artefacts, is very true. I had wanted to explore a different solution for generating the normals, but didn’t have much luck with the heightToNormals node. Given some more time (and the fact I need to get it working for Cassini), I’ll probably figure it out. I’ll update thread if/when that happens.
