Will I ever render this scene? 91pass - 11hours

[Paul Oblomov]

What a great new version It is the first time I see such freaky simtime. (version from 31 may - works)

I uploaded the scene. Have fun!

Also, there's a problem with adaptive grid increase decrease resolution - when grid scales itself

[Svetlin.Nikolov]

Oookay, so the log shows something is slow in the advection. Can you run this same scene on version 4.40?

[Svetlin.Nikolov]

Increase/decrease resolution seems to work fine here. Are you doing something special? And also, when you install 4.40, is it different?

Hey Paul,

Where have you uploaded the scene? Our support guys can't find it for some reason. You should have received an invitation for access to a gdrive folder via email.

Just to make sure what the issue is once we receive the scene - it's slower with the nightly from 1st of June and faster with the build from 31 May? And there is some issue when the adaptive grid expands?

Thanks!

[Paul Oblomov]

I'm using oldie ftp folder, svetlin I think is ok with this. And scene sim fine with 31 may build (I sim atm with it..). About the adaptive stuff - it is random and close-reopen max helps.

[georgi.zhekov]

Got the scenes, thanks! Unfortunately can't reproduce any of the issues.

For the rendering part, which version of V-Ray are you using? Tested it with the latest official V-Ray from the chaos website and a latest Phoenix nightly and works fine. Could it be the GPU driver somehow? Which version do you use?

For the sim issue - tried the builds from 31 May, 1 June and today and all them sim for around 3 mins per frame on a Ryzen 2700x. Does it the issue reproduce with the latest nightly?

Also just a note that the ftp where you have uploaded the files is a very old address, that is now deprecated, so in the future please use the new credentials that you have received in the mail from our support team.

Thanks!

Interesting, I installed todays nightly and it works. Maybe it is gradual slowdown I experienced last time. There's something wrong for sure, I just don't know what. Hope we will manage it one day. I think there's smth with 3dsmax session length...

About vray - you don't have black triangles on meshes ? You can see 'em on the video above. 465.89

P.S. Even 1june build works now, the only difference - I rebooted....

[georgi.zhekov]

Huh, strange. Everything looks good here.

[Paul Oblomov]

Maybe moblur is turned off somehow. But is here. I remember I had same issues with moblur and black triangles with meshes even from h, I just forgot to upload scene.

[Paul Oblomov]

I catched grid increase-decrease bug.

[georgi.zhekov]

I can't reproduce the black artifacts. Which version of V-Ray is that?

About the increase-decrease bug - do you have any steps for that? Is is reproducible all the time or only sometimes?

[Paul Oblomov]

Any vray version. So, you're telling, that you open my scene and checking motion blur=on then press render - you don't have black triangles ? You sure? Frame 0 for example. vray_adv_51003_max2022_x64_30806_install
increase-decrease - random just sim all day with constant tuning

[georgi.zhekov]

Yes, no artifacts here. Do they reproduce if you use Cuda, Cuda CPU? What type of GPU are you using?

[Paul Oblomov]

CUDA is fine. 3090 here,

[georgi.zhekov]

Have you tried different GPU drivers? Out latest recommended one is 466.47
Can you try with that?
