teamrender multiplying light issue

[Nuno]

Hello everyone!

There seems to be a issue/bug regarding the corona light object and team render.
This is what it happens. If I render a image without teamrender the result is as expected. Then in teamrender it looks like the light is multiplied by the clients or some other weird stuff happening.
See the images so that you can have a better understanding of what I am trying to say.

thanks

Might it be the same issue as here: https://forum.corona-renderer.com/index.php?topic=23423

That is, camera exposure is being used for local rendering, but this (apparently - I haven't tested yet) is being ignored when using TR and the main render settings values are being used?

BTW, for cases like this, sharing the scene is super useful, can use the private uploader - details on that, and on useful info, is at https://help.c4d.corona-renderer.com/support/solutions/articles/12000033461-how-to-report-issues-

It seems that the problem is not the same as the thread you pointed. At least I am not using any Photographic Exposure on the camera, just a default and basic one.
As far I have tested, this only happens if you use corona light object. So, HDRi lighting seems correct, corona sky and sun good as well.

The Version I am using is: 3 hotfix 1 (core 3)
I have attached the scene I have used to test the issue.

Thank you

UPDATE:
So, have done some more tests. I have 1 Workstation(windows OS) + 1 node (windows OS) + 5 nodes (mac OS) for this test.

When I render only with the WS + 1 node (windows OS) the result is as expected and correct. Good :)

When I render only with the WS + 1 node (windows OS) + 1 mac node the result is brighter... This is also true if I use all mac. Bad :(

When I render only with the WS + 1 node (mac OS). the result is also brighter... Bad :(

Looks like this might be a problem with different OS on the teamrender?
Am I doing something wrong or not compatible?
Thank you

I can confirm that on my three windows machines, I can render in any combination and get expected results. So it would look like it may be a macOS issue, or one of mixing the OS'es. One thought, can you enable Multipass and divide up Direct, Indirect, Reflect and Refract - I'd be interested to know if those individually are showing a difference (it might be just one of them, which could be useful info).

Meantime, I'll log this internally, and we can try some tests with various OS combinations as a next step (I can't do that here, no Mac :) )

PS, this is just using "Team Render to Picture Viewer" rather than the local server approach for TR?

EDIT - other thoughts, until we can test here
What happens if a Mac is the master machine running C4D, with a Mac as a TR Client? And Mac master, with Windows as a C4D client?
What version of C4D are you using?
What versions of macOS and Windows are you using?

Thanks!

Hi

I am just using Team Render to Picture Viewer on C4Dr20.
Regarding the other questions... I am running the workstation (win10) remotely and at the moment cant say or test those aspects, sorry. Will need someone in house to test and tell me that, which for the moment is not possible.

Here's the results of the multipass you requested.


Hope it helps! Looking forward for a fix :)

Thank you

EDIT: Please do note that this only occurs if you have a light object. If the lighting is only from HDRi or corona sun all seems good.

Works just fine here too sorry to say. So as Tom mentioned, it looks like it might be a Mac issue. :\

[Nuno]

Yes, this only happens when I add macOS machines to de play ;)
