Hi Guys,

Quick questions, someone know how to export a openVDB sequence from the maya plug??? For me is working only one volume not a animation.

For Volume Animation, "BE_VDBWrite" for frame sequence in output for example "InsertFX_####.vdb" but make sure "Time" graph link to "OpenVDBfromMayaFluid" and "BE_VDBWrite" in order works with frame sequences. More Details: ( viewtopic.php?f=33&t=51681&start=110 )

Working Fine in Maya 2016 but some people said it wont work on older maya.

Thank you very much...I will try on that way I did with a Mel script is working but not all the time is a bit weird...

I have the plug for 2015 and is fine will try tonight "_####.vdb"

here a render test:

Yeah I just had a try doesn't work I use this one for Maya2015 the Besha1 I didn't find a stable give me errors and other issues.
I use one from SOUP website http://soup-dev.websitetoolbox.com/file?id=2271521

Yes just find a easy way "volume. $F4. Vdb"
And it's working perfect

A quick video to how export from Maya ... Sorry for bad english , on the video LOL hahahahaa

I have a different question.

I am able to export vdb sequences and single files (using OpenVdb for Maya in 2017) I can import them into Octane 3 Standalone and render them fine...

Can I render a vdb (lets say generated by OpenVdb... using VDBFromPolygons) using Octane Render by assigning a Octane Volume Medium material to the vdb that OpenVdb VDBWrite uses to write teh file out.... but instead have it stay IN maya and just assign the Volume Medium to it?

In otherwords ... anyway to IMPORT or KEEP the vdb file in IN maya and just assign octane medium to it????

Thanks

Hi Peter,

I don't think is possible on the maya plug to set a open vdb file to render I think they only convert maya fluids for the moment. is missing a read Node maybe we should request for a next release.
I use the plug from soup now is working perfect because Arnold is inclued on maya so the soup open vdb works perfect. for mesh creations and etc. Like for houdini after cached on alembic we can render well with Octane.

For open vdb fluids I think the plug convert to maya fluids I'm not sure but of corse would be great to have a openvdb reader from Octane plug

Best,

Thanks Jo
OpenVdb has a read vdb... but I think it 'links' out to the file so it is not brought in but rather 'linked' to then acted on by other OpenVdb nodes. So you can read on in convert it to fluids, or convert polys to vdb etc... but not actually read it in.


I might give SOUP a try.

This might be a dumb ass question.. but if it Soup reads it in for Arnold to render... can you not use SOUP to import it then just use Octane to render it??

Thanks

So all operation is available for open and you can use with Octane I do in production

here some links:

On "Open VDB for Maya and Arnold" http://www.soup-dev.com/tools.htm

and tutorials :

just a bit of research you can have all hope this help you out.



and here to show with soup you can have the same power as houdini
for edit the open VDB


best,
