Hey! My dual Xeon at work has the same problem from time to time :) I'll try to make a minidump the next time this happens...

2x Xeon E5-2630 v3

32
you can try to add some noise back to the final render... not sure how this will work out...

e.g. https://www.slrlounge.com/remove-banding-photoshop/

33
I cranked the images up a bit and now it becomes clear that the denoising in the final render introduced some banding...
often a little additional noise is used to reduce banding artifacts in 8-Bit images

some options:

1. decrease the denoise-amount to leave some noise in the background to reduce banding
2. add a "beauty" render element with denoising set to 0 and mix them in the post
2. save as 16-Bit Half or 32-Bit Float EXR and dither in the post when converting to 8-Bit

any news on the very high memory consumption when rendering large stills?
imho, this is one of the biggest problems in production...
i have just looked at the trello-roadmap and it seems that this will not be solved in v2? :/

More infos:

i increased the gamma a bit in post... so the artefacts are more visible...

Resolved bugs / Strange Artefacts with Sharpening
« on: 2018-01-31, 17:08:16 »
i just discovered a strange bug when using Sharpening/Blurring:

Framebuffer looks great but the saved EXRs show some strange horizontal and vertical artefacts when there is a bright light source...
if i disable Sharpening, everything works fine.

Edit: Corona 1.7 Hotfix 2

Hello everyone,
I come back to my post because really, this window that grows steadily is really unbearable. It would not matter if you worked with three polygons in the scene. But with Forest and Railclone, millions or billions of polygons, it's really very annoying.
The idea is just to add on the VFB an icon like a padlock for example, locked by default. That's all, nothing more.
If this is not possible technically, it would have to work with a normal window, like for a rendering of production.
Thank you !

Again, +1 ! :)

You could use/modifiy the Batch-Script from this thread...

Remote Execution can be done with PSEXEC from the pstools

I need help / Re: dome Hdri
« on: 2017-11-24, 15:43:11 »
Looks like you need to increase the radius parameter of the dome in the Corona Bitmap

Edit: do you have a "Direct Visibility"-Override in the Render Settings?

43
We have the same problem on our farm with the 1.7... some nodes just stay with the "waiting for render to start" status while some some nodes are just rendering fine.
There are also 3ds max crashes from time to time on the rendernodes when rendering DR... All of those errors seem to occur totally random...

DR just feels a bit unstable right now... :/

Only thing I miss from vray is clamp output. That was really easy way to remove fireflies.

hm, i'm not sure, but i think highlight-clamping is for you?

i also experienced that lowering the MSI helps a bit with the fireflies...

Can the material library not come with the installer?
Preventing it from being downloaded every time it's installed on a render node.

https://corona-renderer.com/forum/index.php?topic=15845.msg110252#msg110252

"To prevent downloading MatLib on every render node, you can now manually download the file https://installer.corona-renderer.com/3dsmax/1.7RC2/MaterialLibrary and place the downloaded file to the same directory as the installer .exe"
