For anyone needing help with volumetric light in Daz. using UberVolume
Hope this helps! :)
But i noticed your Uber Volume is under Poser Fornats but the default is Daz Studio Formats > My Library > Shader Presets etc etc
Also if you want to see the volume cone then select it and go in to the surfaces pane and adjust the opacity so you can see it better, then when adjusted to tatse then set the opacity down to 0% again for rendering.
