I'm trying to use a vellum constraint property with VEX to read a per point restlength scale/ I must be missing something simple here, it's not working for me. Any ideas?

but would you associate length with a point tho ? how does a point have a length ?

or try plugging the pink port to your null and check out the spreadsheet, points don't have rest length…but prims…..mmmhhhh

you need to take the values from the grometry that you painted on, (or directly from sops if you want it to update)
...
float factor = point(1, "factor", pt);
...

also you may want to average atributes from both ends

Thanks! Great tip and example hip. Seems to work now, but I'm not seeing much difference when I average the ends. I could be doing something wrong again…
