Thanks for the hint, Frood. And yes you are correct - scene is not being transferred, it has 0 size. Though i solved the “Camera defined but not found” thing by making Free camera with Corona mod on top (it was VRayCamera with mod on top) and this line disappeared , though main problem was not solved.
That´s more than I can achieve here, drServer doesn´t even create any max file in drData 
I will submit that to the Bugtracker when I find some time to test some remaining options.
Good luck!
Sorry to resurrect an old thread, but I am having the same issue, has this been solved?
Hi, first please take a look at this guide if you haven’t done it already and check some of the suggested solutions:
https://coronarenderer.freshdesk.com/support/solutions/articles/5000501666
If nothing helps, please do this:
completely remove the content of DrData folder, run unsuccessful rendering again, and then send us the freshly-created log files
And send us a support ticket with the content of DrData:

We are also working on an extensive DR fix, which should solve most known problems.
Just I very very minor suggestion - I had the same problem with DR before:
I saw that from my 3ds max asset tracking, some bitmaps had only a file name but not a folder where they are.
This made my DR-images become “striped”, 30% darker etc.. After I fixed the paths: no problems.
I use Gamma 2.2on my workstation and in my farm computers there is just 3ds max & corona 1.2.1 installed, I havent started 3ds max there and I havent played with the gamma controls on them.
But is it possible that if my workstation sends a DR-file to the farm computers, could they somehow be rendering with Gamma 1? (When I had the stripe-problem I wrote about it and someone said to check the Gamma values…)
