Smooth shading gets ignored in cycle render While working on a Model I stumbled upon this issue:


This is the first time I see this error and I couldn't find any immediate solution.

I checked if there is any sort of modifier or condition on the mesh which could result to this.

I found nothing.

Thanks in advance.
I dont know what it is, but the problem comes from the "use subdivision" in the "displacement panel" here.
At the bottom of the picture below, just uncheck "use subdivision".
