[Max] I need help! / random black buckets in corona caustics animation

« on: 2021-06-02, 16:16:16 »

Hi there.
I'm rendering an animation with caustics. When i render one frame locally everything looks fine. When I render animation in our render farm (each node renders one frame) random black buckets appear in each frame.
We have all the software and plugins in each node well setup, any other animation without caustics works well, it just fails when we activate the caustics.
Any light on these issue?.
Find attached the frames
Thanks in advance

[Max] I need help! / Re: Corona not using all the threads (Threadripper 3970x CPU)

OS Windows 10 Pro
3ds max 2020
Corona 6
Forest Pack
RailClone

TRX40 Motherdrive
Threadripper 3970x
64Gb DDR4 RAM
SSD Drive
1Gb LAN
I don't know what else could be useful.
I 'll try to see if the error replicates in the 3990x nodes opening and rendering the scene directly there.
Any info will be appreciated.
Thanks

Thanks for the fast answer.
Yes, this is grabbed from the machine displaying the pop-up. It was rendering locally when it did pop-up.
So, as far as I understand, there's no problem for Corona using all the threads, even it shows the warning pop-up and the CPU is only working at 68%?.
Is there any known bug about it?.
Thanks in advance

Hi there.
We have a warning in Corona log which says Corona is using only 39 of the 64 threads available. And that I should click there to use all of them.
We looked into the resource manager and detect that, even clicking the warning to make use of all the threads, the CPU is only using 68% of its resources, when in other nodes is using (when rendering) 100%.
The problem is even worse considering we have two extra render nodes with 128 threads each (3990x), which are sitting there doing nothing.
Is it a known issue due to incompatibilities?, is there any workaround about it?. We need to solve this.
By the way, we have set -1 in System #of threads override.

Thanks in advance
