seems to be linked to normal maps and how it reflects something, idk what that something is tho

[treeofdeath]

seems odd to me, it doesnt do it with every model i own but sometimes this sort of shadow rim-like thing happen. super spooky

[treeofdeath]

i have tried playing with every settings on it, lights in unity and etc. but it just doesnt want to give up

[treeofdeath]

happens after setting a shadow ramp, ill experiment a bit more

[treeofdeath]

fixed it via remaking a new gradient linear shadow ramp, ill close this and say im sorry for my own stoupidity, hope it can help anyone in the future who has this issue

[Xiexe]

The reason it fixed itself upon making a new ramp is because the script clamps the ramp. It sets the wrap mode to "none."

What you're seeing there is the ramp UV actually bleeding into a wrapped version of the ramp, so it goes from 0-1, and then bleeds over a bit back to 0.

The fix, for future reference, is just to set the wrap mode in the import settings of the texture.
