Rendering problem

[lamerehic]

Hello,

I got a rendering problem with octane 2018.
Cannot render my sequence, got a failure error first each times i tried to launch the rendering,
and now it hangs for ever on this screen:

Someone got a idea?

Can you please enable the Octane log in the plugin options panel to check if Octane is reporting some kind of error? If you have the denoiser enabled, you could disable it to check if it is the source of the problem.

Thanks,
-Juanjo

A system reboot could also help in some cases.

Thanks,

I turned off denoiser

Hmm, usually this error comes from a hardware, system or Nvidia drivers issue. Have you updated the Nvidia driver lately or something like that?

Thanks,

[lamerehic]

Ok the errors desepear after a update of the drivers...

Should have thought of this...
thx juanjgon!
