CopyStamp Issues with CVEX

[Annon]

I'm not sure if it's just my brain being a little fuzzy today, but I can't work out this seemingly simple workflow with CVEX.

Basically I am going to have a cluster of points and copy a volume to each point to make up a cloud. I want to use CopyStamps to randomise offset of noise etc and view it in the viewport, then at render time just render the volume procedural to get the best detail.

Problem I have is using the volumeVop linked to the shopnet stuff and still being able to get copystamping working.

Any help would be much appreciated.

Thanks

P.s. I've added a simple scene to explain what the problem is.

copystamping can work only in houdini, so if you want to just use shader based CVEX and vary some parameters to get different volumes copied on points it is perfectly possible

but if you want this to happen at rendertime as well, using volume procedural, you will need to have volumes instanced on points and vary the CVEX based on instancepoint() expression

here is the example of the setup where you have copied volumes randomized by copystamping for viewport visualization and at the same time they will render as instanced volumes with the same variation using the same CVEX shader
