Hi All,
i made the initial openvdb plugin connector to Softimage, currently its version 0.8 because of not fully tested and can be buggy. Also, many tools from openvdb lib is not implemented yet. Many thanks to houdini connector authors and Steven Caron for snippets of code. What is the Openvdb and its capabilities you can see here:
http://www.openvdb.org/documentation/
And be sure to check out the coolest dreamwork pdf on the subject :-)
http://www.openvdb.org/download/openvdb_dreamworks.pdf


Here is my little test on rendering houdini's explosion inside of xsi with arnold:

You can download plugin ( free for comm and noncomm purposes of course ) here:
https://dl.dropboxusercontent.com/u/37160275/OpenVDB_to_Softimage_v0.8.rar

The arnold shareds are compiled against sitoa 3.0, the sample scenes is for 2013 and up. The redistributable required as always http://www.microsoft.com/en-us/download/details.aspx?id=30679

cheers

The Dreamworks PDF looks amazing. Can you tell in succint way what you think what should be the integration steps in Softimage?

I think LS animation to fog, Combining grids, volume stamping , volume deformation, particle surfacing seems most interesting, this only after a cursory look.

i don't follow, 'integration steps'? oleg did the integration of the library into ICE, you have the tools to manipulate volumes now.

Fantastic toolset, thanks so much! Quick question: what's the correct Ice node combination to write vdb grid data out of ice (so you can read it back onto the shader). Found the io node but not sure what you plug it in to?

@wotty33
it's pretty straightforward, all what you need is to put some grid on input, set "Write" mode, specify your .vdb file name and name of your grid, and make it all evaluating. See the screenshot for example


@Bullit
I misunderstand this too, can you rephrase it please ?

Thanks a lot! This is so useful. It's the perfect solution for a couple of shots I've got going at the moment. Now back to the turkey.(or veggie nut roast in my case)

Happy Christmas from the uk!

Cheers, Paul

Thanks for feedback. Following that quote i am thinking that some capabilities that appear in Dreamworks.pdf are missing.

amazing work so far, fluidy volumy stuff is what softimage needs the most especially on the rendering side.
