SOLVED - Volumetrics - VDB Explosion Not Showing Following Livestream

Diomede

Greetings.  I am trying to get a VDB explosion smoke effect.  No luck thus far.  I am following the method of Jay's Livestream video in the Daz+ forum.  My VDB file is the same as his, downloaded the explosion sample from openvdb.  Following Jay, I loaded a cube in my scene and used the geometry editor to change the default shader name to Volume.  The explosion.vdb file is loaded in the volume file channel.  I have tried it with Clip to Geometry both on and off.  The smoke volume does not appear in the viewport or render.  I must be missing a step.  I am using Daz Studio version 4.22.  Jay's Livestream example used version 4.20.

Source for VDB File.

You haven't defined proper Color in Multipliers of Scattering and Absorption...

That was it.  Knew I must have missed a step.  Appreciate the help very much.  

Thank you, @felis and @crosswind, for taking a look and helping me solve the problem.  

Cheers.
