[Max] Resolved Bugs / [solved] Constantly growing rendertimes in animations

« on: 2022-06-21, 16:53:08 »

Hey,
I installed ver 8. last week, and I experience the same problem, which I had with ver. 6 earlier. When rendering an animation of a very heavy scene, with lots of forest pack objects, and heavy geometry, the rendertime is slowly growin frame-by-frame.
For example: 11:20, 11:32, 11:39, 11:50, 12:08... etc.
this was an issue before ver. 7, and with ver  7, (maybe hotfix1) the problem was gone. Now, after installing ver. 8 this came again, and it's very frustrating.
I'm rendering on a small farm, 5 computers. The problem exists on all comuters, each node, and the workstation also, with different configurations, so this is not a hardware problem.
I've tried it with backburner and with pulze render manager - no difference.
Can I switch back to version 7 until the problem is solved? Can I use the same licensing, the chaos licence manager?
Thanks in advance.

[Max] General Discussion / Network rendering speed/network storage

« on: 2021-12-28, 12:14:52 »

Hello,
I need help or advice, how to properly set up network rendering with corona+3dsmax+backburner. I'm doing this for several years now, but now, i have 1 workstations and 3 render slaves, and it semms, that the network speed affects the rendering speed. My rendering speeds are inconsistent. Sometimes, my Threadripper 3970x renders the animation with the same speed, as my Ryzen 3950x - which could not be the case, since the threadripper is basically twice so fast. However often this is the case.
I'm starting to think, this is because all the assets are stored on the workstation. The asset paths are all network path, and the slaves are getting all the assets during rendering from the workstation. I have a standard gigabit ethernet network.
What do you think, could this be the reason, why the threadripper 3970x is not rendering faster, than the ryzen 3950x? I mean, that, the slaves are not gettig all the assets fast enough during the rendering? I'm rendering very heavy scenes, with lots of proxies, large textures, etc.
If I would use a NAS, would it help? Does any of you have a NAS properly set up for this usage?
Thanks!

[Max] General Discussion / Corona Sun darker than sky

« on: 2021-11-05, 19:18:59 »

Hi,
I try to render a scene, where the sun is directly in front of the camera - kinda sunset scene. No matter how I tweak it, the sun is always darker than the sky, and I don't know why. No matter how low the sun is, it should be brighter than the sky. If I set the intensity stronger, the sun will brighten up the scene, but the visible disc remains the same dark yellow...
This way, I can't use the bloom and glare settings eighter, because the sun disk is dark, so no bloom or glare on the disk. Anyone had this problem? What I need, is a bright sun, in front of the camera.
Thanks!

[Max] General Discussion / Weird rendertimes when using Backburner

« on: 2021-10-14, 09:57:50 »

Hi,
I'm using backburner to render animations, I have 2 rendernodes, and 1 workstation. Rendernode1: amd 3950x, rendernode2: amd 2970wx, workstation: amd 5950x.
On my last project, the rendertimes, most importantly the parsing scene times look like this:
3950x: parsing scene 00:40 sec, total rendertime: 4:50
5950wx: parsing scene: 1:30 min, total rendertime: 5:10
2970wx: parsing scene: 3:24 min, total rendertime: 7:01
So, that's weird. Parsing scene is a single core task. How is the 3950x faster, than the 5950x? It should be the opposite.
I know, the threadripper is slow in sinlge core tasks. But the 2970wx needs 6 times longer to calculate parsing scene, then the 3950x. 6 times longer, How can this be?
All the assests are on the workstation (5950x), the rendernodes get the files via network share.
I ran also cinebench tests singe and multicore. Those times are OK, as they should be - 5950x is the fastest, even in single core. So there is someting with Corona render or max/backburner which causes weird rendertimes. Any advice? thanks.

[Max] Bug Reporting / Scene parsing getting longer

« on: 2020-10-16, 23:42:29 »

Hi!
When rendering animation over Backburner, the scene parsing is getting longer and longer with every new frame, on AMD cpus. I've got a Threadripper 2970wx, and a Ryzen 3950x. Both are having this problem, the 3950x is worse.
On my Intel cpu, the scene parsing time is constant throughout the whole animation.
Please, help! Any advice? Thanks.
EDIT: the CPU usage on the 3950x is really low, when parsing scene - around 5-15%. On the other CPUs i'm getting 45-55%. WHy is that? The same scene...

Hardware / TR 2970wx vs. Ryzen 3950x

« on: 2020-10-16, 23:31:24 »

Hi there,
I've now 2 rendes slaves, one is a Threadripper 2970wx, the new one is a Ryzen 3950x. Theoretically, the threadripper is faster in multithread, and the ryzen should be faster in single core calculations. Measuring with cinebench this is the case.
Now, I'm rendering an animation. After ca. 20 frames the threadripper is much faster, even at single core, at scene parsing. For one reason, the scene parsing time on the ryzen is gettin longer with every new frame. This is weird, since the ryzen should be much faster in single core.
(The scene pasring time is also getting longer on the threadripper too, but not no much, as on the ryzen.) My worstation is an Intel, the are the parsing times constant.
Does any of you encountered something like this?
EDIT: CPU usage on the 3950x is REALLY low, when scene parsing: i get ca. 5-15% during the parsing process. On the 2 other CPUs, the usage is 45-55%.
Thanks :)
