VDB volume surface not offering file tab - Solved

Diomede

Greetings,

Has probably been asked before.  I am following the VDB video on the Daz blog.  I opened Studio.  I created a primitive cube.  I used the geometry editor to change the name of the default surface to Volume.  I used smart content to find the Daz resources.  I applied the Simple OpenVDB Volume shader.  I went to the surfaces tab.  I highlighted the volume surface.  There is no tab for the volume file.  I tried clicking the Simple OpenVDB again making doubly sure the cube was selected.  Note - I downloaded a sample VDB file from OpenVDB, but there is no chance to use it yet because I can't find the slot on the surfaces tab.

I must be missing a step.

UPDATE

Don't know why, but now it works.
