[Sidefx-houdini-list] volume from sops in dops?

So far we have two solutions:

1)empty geo>sop geo (volume sampling)>volume
2)sop scalar field (calling in the sop volume)>apply data< empty smoke 

Both work well for different cases. Both will sample based on the volume 
they are being used in.

Thanks for the help everyone.
