We use 3ds max plugin For some reason when octane slaves kick in Octane viewport turns white and it renders white. (very overexposed ) Why is this?

slave version 3.02

seems like all this happens when i am using scattering medium With sun kind - MAIN Type - Daylight or texture

Sun just gets very bright until screen turns white. This happens only when slaves are rendering too.

When scatering medium is empty it works

We tried the latest version same

Also we get instant errors on slaves (see attached) but they continue rendering

Slaves render fine with 2.23.2 - 1.9 version. It's just once slaves kick in sun in the rendering gets brighter and brighter and in about 2 seconds image just gets white

I could reproduce the problem here on Maxwell and Pascal GPUs, but it's probably a bug on our side. I assume that your slave is running Maxwell/Pascal GPUs and your master some Fermi/Kepler GPUs?

Hi yes. Master is two old titans. And slaves have combination of 780tis and 980s

Thank you. Hopefully it can be fixed soon we got so many projects to render.

Ok, I have found and fixed the problem. It only occurs with the direct lighting AO kernel if you use an environment medium. So until we release the next update, you could switch to diffuse GI or use path tracing.

Thank you! Yes we did use AO.
