Open VDB Installation instructions
There is some confusion about installing, I hope it makes sense, let me know. These is for the updated tools, the way Besha explains on his Youtube is deprecated since in the mean time he packaged them more elegantly. And as always thank you Besha, without you all our clouds would be gloomy.
(ovdb folder is the one you unpacked from the download, 2016.5 could be 2016, USERNAME depends on your user, this is the default install directory for Arnold if your is different use that folder to copy shaders and extensions and the folder at step 1 can be anywhere else and named anything else, you choose, just make sure that the mod file you copy to your maya user folder points to it :) )

1. create folder:
C:\Program Files\Openvdb for Maya

2. copy
all from
ovdb\maya\2016.5\
to
C:\Program Files\Openvdb for Maya

3. copy
C:\Program Files\Openvdb for Maya\maya20165.mod
to C:\Users\USERNAME\Documents\maya\2016.5\modules

4. edit C:\Program Files\Openvdb for Maya\maya20165.mod
make it point to the folder created in step 1. like this:
+ maya2016.5 1.0 C:\Program Files\Openvdb for Maya

5. copy the shelve file: shelf_OpenVdb.mel
from
C:\Program Files\Openvdb for Maya\shelves\shelf_OpenVdb.mel
to
C:\Users\USERNAME\Documents\maya\2016.5\prefs\shelves

OpenVdb for maya plugins installed. Now to install openVdb shaders and extensions for arnold, these are required.

1. copy
from
ovdb\arnold\mtoa\2016.5\extensions\
to
c:\solidangle\mtoadeploy\2016.5\extensions\

2. copy
from
ovdb\arnold\mtoa\2016.5\shaders\
to
c:\solidangle\mtoadeploy\2016.5\shaders\

Load plugins...


(let me know if it works or not and I propose to pin the topic if useful)

VolumeOpenVdbNode
I got it, a workaround is to create that node with mel command:
VolumeOpenVdbNodeCreate;

If created by pressing TAB and typing in the node editor, then you get the error I got. Hope that helps.

open vdb 2016-01-20
Can someone help me with installation? I am getting tons of errors with VolumeOpenVdbNode.
I am using arnold and can't seem to render a thing with it. Thank you

Edit: managed to remedy the errors by using the command VolumeOpenVdbNodeCreate; instead of typeing in the node editor.


But I can't load any volumes. Arnolds volume is rendering fine with volume collector shader while VolumeOpenVdbNode does nothing. No viewport preview. Volume path is set in this format: vdb\fire.####.vdb
VDBRead and VisualizeShape also give nothing in the viewport.
Read is connected to Time node.
Am I doing something wrong?

VolumeOpenVdbNode
Once inside of the attribute editor I get tons of errors and the node can't load any vdb files.
Maybe its an error on my part, but the rest is installed and works fine. Win 10, arnold and maya 2016 sp6. Tried to install 4 different ways, always the same problem.
