Black pixels when rendering with Arnold

[wierdhofstrawh]

Hello everybody,

Recently i started rendering a model of a house and i have a problem.

When rendering black pixels appear on one particular plane i've drawn. The other planes are fine but this one isn't. I tried to change the displacement and normal maps but it didn't work. I also increased the Ray Depth in the render settings but it also didn't do anything. 

Below i uploaded two screensaves together with my render settings. 

I hope somebody can help me because i'm lost. Thanks!

Kind regards,

Wierd

A couple of things that standout. First your Arnold Version is old, really old. You should be on version 4.3.3.21.

Then the black pixels to me, seem a missing material or a missing bitmap. Would be useful to share a log so it is easier to identify that.

Hello,

Thanks for your response, he problem is solved.
The problem was with one of the forest objects that was added to the plane.
