trying to blend two diffuse materials, a yellow and a blue, using ISL

Code: Select all

def eval() real :
let
	c = clamp(meanCurvature(), 0, 1000)
	z = normalWS().y * 3
	z2 = z * z
in
	clamp(if (z > 0, z, z2) *
		noise01(normalWS())+c,0.0,1.0)

here is the result


- -

but if I only change normalWS by posOS, there is no blend
