Rensei: Sketch #54

[Rensei]

Oh absolutely! I had this problem few weeks ago and read that thread so many times haha. For polar coordinates in my shader I decided to just calculate the derivatives like advised here: Best 'Polar' option to save pinched triangles - #12 by fleity

@fleity

You calculate ddx and ddy of the regular uvs and use a different sampling function tex2dgrad() instead of tex2d() (which isn’t a node in shadergraph for some reason, but you can simply use it in a custom function node).

For the above thingie I don’t use polar coordinates from the shader so the noise is sampled as usual

Thanks for the link tho, that topic is super useful~
