Live viewer + network rendering black parts

Hi.

I have a small, but disturbing problem when working in live viewer and using network rendering. There are parts of the render viewer that are black while refreshing the frame.

Here is a screen recording: https://dl.dropboxusercontent.com/u/254 ... roblem.mp4

I am using the latest version of Octane and have 2 slaves with 3 and 2 gpu's. I am using 980ti's and 1080ti's. The probelm is the same even if I change slave/masters between them.

Here are the render settings:

Thank you!

I would assume your network speed is too low. Are you using at least 1GB connections?

Yes. The connexion is via ethernet cable at 1GB. It dows the same with every scene. Couldn't find anything in particular.

I have discovered that if I decrease Max tile samples it works better, but still get black areas.

Hi Yan,
in general, I prefer tonwork with a very lower value of the Max tile samples while setting up the scene, and rise it to the max only in final rendering.
But I have never seen those black areas with net render :roll:
What about the PCI bus speed of the slaves?
Do you have only one GPU in the Master for both displays and octane?
