I updated this for Houdini 20.5 and added a "stopped" attribute of 1.0 if the particles are less than 0.05 from their target.
Seems to work.

Bump for April 2024 now that Redshift supports rest position inherently; trying to set up the RS OSL Triplanar Coordinates from their Github [github.com]

My textures are swimming, and my geo is deforming over time. I have a load of cloned softbodies going through vellum, so at some point in the network, I've added a Rest SOP with a TimeShift set to frame 0 into the second input, and it's set to store the rest and rest normal. That should mean I freeze frame zero as the reference frame to be able to stick the RS TriPlanar node to deforming geometry. The point of using the OSL node is just to try to eke out more control over the setup.

Supposedly this is all you need in Houdini to allow the State node to pick up the rest and rest normal as Reference Object for the TriPlanar node (or indeed, TriPlanar Coordinates OSL node) to stick the triplanar to deforming geo.

Alas - this is not a documented workflow in Houdini (it's barely documented in C4D either tbh). Any ideas?
