can work for both, but at it's made to work in 2d space, it's better suited for SD
For SP or SD ?
Ha good to know: do you have the link so I can see if there is still a reason to leave mine?
I hate to be the bringer of bad news, but there is already an SD node called "Light" that does this.
Hi Vincent, this node looks very close to what I am looking for to generate anisotropy angle maps. I am now looking for a way to combine this with the Tile Sampler to create a Tile Sampler node that outputs anisotropy angles to match the sampled output (when using the Vector Map Input). If such a thing already exists please feel free to point me in that direction.
