When I render a scene with dr enabled it works fine if I render from within max, but if I send the job to the back burner queue it still renders on all machines, but the nodes aren't sending data back to the master.  On the render progress window dr shows 0 updates and 0 passes from all nodes.

I've checked the corona log on the nodes and it shows that the nodes are rendering the prepass followed by pass 2 over and over again.

The steps to recreate are:

Open batch render in 3ds max,
Create a job
Submit to net render
On net render screen connect to back burner manager on the local machine
Choose the local machine as the server also (checking use selected server only)
check enable rendered frame window.
strip rendering is de-selected.
Submit.

Everything renders fine, it's just slow as the nodes are rendering but not contributing.


  • backburner render time 7:07 80 passes (dr enabled)
     
  • max locally  same scene and render settings, render time 7:07, 180 passes

It's not a network error, and backburner works fine with mental ray dr.  It's also not scene releated as it happens on all scenes.

Max 2017 sp3 back burner 2017 corona 1.6

Does anyone know how to resolve this?

here's part of the log when it's working properly when using dr directly from max instead of backburner.  The only difference I can see is that it's receiving a sampling mask.

2017-05-15 23:30:54  DR slave received sampling mask, region 0 1974 5333 2068

after more testing, i've found that the problem only seems to happen if I use batch render.  When submitting to network rendering from the render setup dialog then everything works as expected, and all nodes contribute.  Bug?
