this is coronamax log:


2020-10-05 17:25:33  This scene uses legacy (pre-v4) medium/refraction resolving that is not based on geometry normals and produces incorrect results when multiple medium containers are intersecting. The scene was loaded with the legacy behavior to make the rendered result more consistent with older versions of Corona, but we strongly recommend switching to new behavior using the button below. If normals orientation is correct, switching will preserve or improve the look of the scene.

How exactly are you using both Corona's DR and Backburner?

Can you send full logs? https://coronarenderer.freshdesk.com/support/solutions/articles/12000002065-gathering-dr-logs

[jjaz82]

From a workstation i send a job with DR to a master node on render farm, where it's set up an backburner server and master.
here a screen of node and all full logs

[jjaz82]

I tried, the problem happens even if I launch the animation without backburner.

I can see these errors:

2020-10-05 16:48:49  Cannot load UHD cache from file. New cache will be calculated from scratch.
Error: Cannot open/read/write file '//NAS/Scambio/nicola/animazione/test/uhd.uhd'

Can you try with path tracing only (path tracing as both primary and secondary GI solver in the Performance tab) and see if the issue persists?

If it does, please send us the scene and we will see if we are able to replicate this behavior:
https://corona-renderer.com/upload

[jjaz82]

yes, also with path tracing.
the scene was uploaded
thank you

Hi maru, have you receved the scene?

[maru]

Sorry for the delay. Yes, I have the scene and will look into it ASAP.

[maru]

Looking at it now, it seems that you are using Corona Renderer 6 (non-hotfix) and its DR server.
In Corona Renderer 6 Hotfix 1 we can see:
"- Fixed DR getting stuck when rendering the second frame of an animation"

So please download and install Corona Renderer 6 Hotfix 1 and its DR server and try again. The best idea is to un-install the non-hotfix version first from the Windows "Programs" list.

Hope that helps!

hi maru, thank you for reply.
it's very strange, I felt like I had the latest version installed, i try how did you say.
