Rhino Octane 4.0 issue with Displacement going black Tweet

[andrebonnice]

Hi Paul,

Just been experiencing this issue with the latest Octane for Rhino (its never been an issue before). When using a displacement map some of the areas not displaced turn black, see images below:
One with displacement turned off and one on. The strange black areas don't appear everywhere just randomly. I've tried this on both RH5 and RH6 with the same issue happening.

Hi. Can you provide a sample scene and displacement map which produces this error please, and I will take a closer look.
