VDB Volume Grid

[haniel1107]

Hi, just like to ask, if fire and Volume Grid should work. As I tried it hard...
but, I need to mention that I have no experience with VDB and can't find anything helping for fire.

Smoke works, but rendering crashes always after a few frames of any animation... thanks for any tips or information..

(PS: Every VDB exported with x-particles)

Hey, can you send over one cache file that crashes for you?

Nothing should crash, so we gotta fix it

Thanks!

Hi,
thanks, I will prepare a file ...

Means also fire should work, too - right?

[Svetlin.Nikolov]

It should, yes, but maybe there is something specific with the xparticles vdb...

Hello Svetlin, I could made fire after more trying's.. thank you.

But my VDB Animation Sequence is still crashing. The whole animation is 125 Frames @25FPS and after around 27 frames it crashes randomly... tried many times now..
I tried also Chaos cloud, but it seems that ChoasCloud does not support vdb's...

I collected all necessary files and uploaded them in a zip to my dropbox.
I will will send Shaio a PM with the link. If you could try it or find out what's wrong it would be much appreciated.

Thanks for your help..!!

Awesome, thank you! Will check it and get back to you with more info.

Chaos Cloud Does support vdbs. Can you describe what kind of an issue do you have exactly when submitting to the Cloud?

Cheers!

Also can you send over the job id from the Cloud job portal so we can check what is going on?

Thanks!

Hi Svetlin,
thank you!!

Regarding cloud, I tried only one frame, but the smoke was not visible in the rendering.. I've submitted through the send to cloud button in C4D Vray tab.
Good to know, that ChaosCloud should support it...


Please see attached, one screenshot from the cloud, one how it should look...

Thank you!

PS:
It isn't an urgent request, this is no official job... just try and learn Vray5

Thanks!

Hello Georgi, it is the same job, where I send the link to Shaio...
hope this helps... if not, just let me know...

Thank you!

PS: Does it matter, that I tried only, render current frame on the Cloud? Tried frame 28 only, as this crashed many times?

Please see attached, one screenshot from the cloud, one how it should look...

I just like to add something to the screenshots.
My Focus was just on the vdb, but it looks like the floor texture and the motion blur is also missing.. talking about this ChaosCloud frame only..

Attached local render without any post..
Thanks

[haniel1107]

Hello, just want to ask if you've made any progress ... thanks.

[haniel1107]

Sorry to ask again... but could you find out what's wrong?
The reason why I played around was to see how it works.. I would need to use vdb support to create some offroad dust...

Hey haniel1107 ,
we're still working on this one and looking for the cause of the crash. We did fix the problem with Chaos Cloud rendering the current frame only. The fix is included with the latest Hotfix 2, so if you've updated then you should be able to render more than one frame in Chaos Cloud. We will update the thread when we have more info on the crashes.

Hi Shaio, thanks..
..does chaos cloud now also renders the VDB?

Hi Shaio, thanks..
..does chaos cloud now also renders the VDB?

Yes it should be rendering the vdb files. Previously it was rendering only the current frame where now it should render the whole sequence as intended.
