[Max] I need help! / Animation flickering

« on: 2021-02-17, 09:17:06 »

Hey

I need help to get rid of flickering in my animation. My noise threshold is 5% and I use default denoise values. The flickering is most obvious on the white walls. The scene and video is attached.

[Max] I need help! / Make steam / smoke / small fog

« on: 2021-02-09, 14:52:38 »

How would one go about making coffee steam without using Phoenix? I'm interested in both still image and animation but really dont know where to start.

Something like this https://image.freepik.com/free-photo/hot-coffee-cup-tea-steam-vapor_101276-151.jpg

Do the problem scenes have the thousands of animation layers as before? Did you install the cleaner script in the startup to make sure those were always removed?

I have used the script yes, and it makes no difference. However I do not have it as a startup script. How do I do this?

If only when rendering, does the freeze start right away or only after rendering for a while? (Could be an overheating issue throttling the CPU in that case, what are the temps?) What is the CPU usage when rendering?

It starts to become slower the first 30 seconds or so, and then it totally freezes for minutes at a time. Could be an overheating issue yes, I do use a laptop... I have not checked the temps, will definitely do that. -> Checked now, the CPU-usage is 100% and the temperature is 95 degrees Celsius.

Are you running a firewall or anti-virus? What other things are running at the same time?

I run nothing at the same time and have uninstalled the default anti-virus software from Norton.

Is the Material Editor open or closed while you render? Are you rendering single frames, or animations? While there was no out of memory issue in the one scene in that previous thread, what is memory usage like in these other scenes that have a problem?

Material editor is closed and I render a single frame. I am not sure of the memory usage but I get no errors or warnings from Corona.

You can capture a minidump when things are freezing, see https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max

You can override the number of threads used in rendering, to see if that keeps things more responsive (https://coronarenderer.freshdesk.com/support/solutions/articles/12000019240-where-are-the-system-settings- )

What would be a decent amount to test with? Im not that technical...

Hardware / Computer freezes during rendering

« on: 2021-01-18, 19:47:27 »

Often when rendering with Corona my computer becomes real sluggish. It freezes for several minutes before even the mouse cursor moves. If I forget to set a time or pass limit I am pretty screwed since it will be real hard to stop a render when I can see the movement of my cursor once every five minutes. If I do set a pass limit, the computer freezes totally until its finished. It is impossible for me to work this way. But strangely this only happens about half the time. The other half it works perfectly fine! I can give up one day because it doesnt work, and the next day when I open the excact same scene everything is fine.

I have posted this problem here once before (https://forum.corona-renderer.com/index.php?topic=31786.msg179432#msg179432), but have since rebooted my computer totally and installed everything from scratch. Could this be a hardware problem?

My specs are:
Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
32 GB Ram

I run 3ds Max 2020 and newest version of Corona, both on student licenses.

There are 2165 animation layers in that scene, maybe that's your problem. Use this script

https://forum.corona-renderer.com/index.php?topic=19797.msg130003#msg130003

or any cleaner script dealing with animation layers.



Good Luck

Thanks, this didnt help unfortunately. I just run the script and it works automatically in the background right? I didnt know i had any animation layers, where can you see this? I dont mean to have any animation but I have imported some of the assets so they might have some animation on them which I am not aware of.

Intel Core i7-9750H - 6 x 2.60 GHz
GeForce RTX 2060
And I just updated to 32GB ram. Can this be the problem?

Hello,

I just started using Corona renderer and experience that my computer becomes really sluggish when rendering a really simple scene. This was not a problem when rendering in a previous project which was quite heavy. I am using Max 2020 and a demo license for Corona 6 hotfix 1 (demo license). I have 32 GB ram and dont get any warnings og errors when rendering.

Hope someone can help me.
