Toon shader tangential shadows

[white fog]

i made a custom toon shader to use on terrain but im getting these annoying artifacts around where the light is tangential to the geometry. is there any way to prevent this from happening

[peak needle]

I already explained it though
Something still unclear?

[white fog]

no i just put it here just in case someone has a magical solution for it

ill just disable shadows unless i figure something out

[peak needle]

Modifying the toon ramp to hide the shadow threshold is likely as magical as it'll get

But I welcome more ideas

yeah i did that but it still looks like dookie so i gave up 😔
ill just be covering it with grass anyways so it doesnt reall matter

[peak needle]

It should look almost exactly the same if you have a sharp toon ramp with the threshold near 50%

The casted shadow is covering nearly 50% anyway, and is sharp too

Just the artifacts would be covered as well

one sec something just got screwed up
