Use dual rest fields without Unified noise in H15?

[Neon Junkyard]

I have a smoke sim from pyro with dual rest fields, and I want to use the rest fields as my sample source for a custom noise in a volume VOP.  However with Houdini 14+ the dual rest solver only seems to work with unified noise as it has two outputs, or in houdini 15, a signal output.  I need to create my own custom noise for this project, and the unified noise isn't cutting it. 

 

With older versions of houdini you could use a mix to blend between rest and rest2 using rest_ratio as the bias (see attached for a simple example) but this no longer seems to work and causes popping in the noise as the rest positions change, as it doesnt account for rest2_ratio, or rest2 in general (or so Im guessing).

 

Both the dual rest solver and unified noise have been black boxed in Houdini 14+, so does anyone know how to either-

 

A- recreate the dual rest solver using regular vops

 

or

 

B- get the dual rest solver to work with regular turbulent or anti-aliased noise?

 

Thanks!

try creating 2 noises using rest and rest2 as position, then use the rest_ratio to mix the 2 noises

That actually worked really well, thanks for the suggestion!
