Hey, has OpenVDB been built for Maya 2017 yet? Did not see it on the front page or here on the forums. Would be useful here :)

Bump. Any news? Besha? :)

To be honest this is not very urgent or critical, but would be fun to be able to leverage VDBs in the latest & greatest Maya.

I assume it's the Arnold DLL doing all the heavy lifting in the SOuP OpenVDB release and the plugin just creates the nodes needed to access it so I guess I could write my own C++ plugin to do the same. Unfortunately I'm lacking the time/dedication to do that right now.

This is one of the things I'm toying with at the moment:

my version of openvdb has two packages
one for rendering in Arnold
second to work in mayа to create,change,recording,reading vdb format and so on

in the package for Arnold included
Shader aiBE_VDBArnoldRender
extensions BE_VDBArnoldRenderTranslator (the translator mayа node BE_VDBArnoldRender)
and my version of procedurals volume_openvdb

the package for maya included a lot of nodes and list them makes no sense
yes, the plug-in for maya BE_OpenVDB.mll
need ai.dll
just because I use some functions from the arnold api
for BE_VDBNoise,BE_VDBFlowNoise, BE_TurbulenceNoise,BE_AntiAliasedFlowNoise and BE_WorleyNoise.

for not patient
not final version
BE_OpenVDB for maya 2017 (tested in maya 2017 udate 1)
and for mtoa 1.3.1.1 all only for windows now

Peter: I'm using a school assignment (whole body sculpture) as a platform for tech experiments. The dream I'm chasing here is to be able to sculpt etc like ZBrush in Maya (which would bring added benefits like previewing final lighting with a GPU renderer without export-import hassle as well as leveraging Maya rigging & procedural & other tools).

The key technical thing here is very simple, given one has access to VDB in Maya: I wrote a tiny script that can remesh stuff using VDBFromPolygons-->ConvertVDB, resolution to remesh at is stored as an attribute on each mesh (shape). Makes it possible to work in a Dynamesh-like fashion using the Sculpt Tool brushes. Seems to be working pretty fine with 100-200k polys per mesh before it gets slow. It erodes the mesh over multiple iterations though. Oh, I guess the Youtube description is misleading, the script is not up on the public internet yet.

I was planning to do Part 2 tonight, but mysteriously BE_OpenVDB.mll refuses to load in 2016.5 and 2017 (pre & post Update 1) on my home machine so I'll have to go to sleep and continue at school. When I've spent a couple hours more on this project it should start looking much more like the end goal, a human character.

Hi
The vdb file are not showing in viewport.the file loaded but nothing in viewport.
I can see it only when I heat render.

Any solutions?

in preferences change mode Viewport2.0 rendering engine opengl core profile to opengl
and check  Viewport->Show->Locators on.

Sorry
I can"t send the scene because it exceed the 2 mb that Soup allow
But any way here is the preview, I can render but can't see any thing.
Now I update for mtoa 1.4 and nothing work for vdb no vuewport no render.
Can you complile the vdb with the new API for mtoa 1.4?
