I've already reported that bug but I couldn't send my files because of NDA :
There seem to be another problem with network rendering and render passes : the ambient occlusion pass is messed up when rendering with a slave.
The pass looked washed out, like if the gamme was off, and sometimes it shows "blocks" that are rendered differently in the image.
If I disable network rendering, everything is fine.
Here is the pass when I disable network rendering :

And here is the pass when the network slave is used :

Same cards and drivers on both Master and Slave
Here is a scene that still has the bug, with no NDA object (LW 2020 + Octane 2020.1.0.7) :
- Lightwave scene : https://we.tl/t-A6Plm2LQfa
- Orbx file : https://we.tl/t-Kw8PNBBG0i
Remember that the problem on the AO pass occurs only when network rendering is used.
Also there's no problem when using Octane 2019.1.5.1
