Rest position in pointvop

I'm applying turbnoise to deforming points in a pointvop, even though I've set the rest position upstream I'm still getting swimming. Is this something I need to explicitly sets in the pointvop? Thanks!

The rest position are stored in a separate attribute “rest”, and not “P”. Did you try using that to generate the noise? You can access the “rest” attribute with a bind VOP. The noise should be generated from the rest position, but applied to the deformed geometry using “P” (and probably “N”). See the attached hip file.

Thanks for the response, it turned out to be an issue with the scatter sop randomly changing point order, I was able to fix it generating points in texture space instead of by density
