Mix Mat in 3.08 test 6 broken?

[jayroth]

I am setting up a skin material in Octane 3.08 test6.0 using a glossy material and a specular material. If I apply either of the materials onto the mesh, I get the expected result. However, if I apply the mix material that contains the glossy and specular materials, the shading shows a harsh line splitting the mesh in half. I am stumped. I have also tried the new Uber material, same result. Any ideas?

Material 1

Material 2

Material 1 + Material 2 at 0.5 mix

Found it. Displacement causes this.
