Fresnel in material layer - Invalid node PixelNormalWS used for normal input

[phil123456]

Hi,

I am new to material layers, I have a material with two layers

when I added a Fresnel node in the bottom material, I get errors

• Invalid node PixelNormalWS used for normal input
• Invalid node used in vertex/hull/domain shader input

I dont understand how to solve this

bottom material

top material

blend material

any help appreciated

thanks

The same issue here

Trying to use it in LayerBlend, preview works but when inserted into material it doesn’t work, says the same about CameraVectorWS.
