hi yall
very excited about POP grains…
the only problem i seem to b getting when using granular solids/sheets/strands is I am unable to pin some points to their internal animation.

the target stiffnes and target P attributes will only pin selected points to the position on frame 1…animating the target P attribute has no effect after frame 1.
the same applies to having a vector attribute in your sop geometry,only the values on frame 1 will be read…..

anyone with a solution?

thanx in advance

Hi thexon

Update of the pin in the animation seems to work. Take a look attached hip file.

Thanks for the response.
Ur file is interesting,but not exactly what i wanted.
Ur pinned points are stationery.
What i was trying to achieve is to have points that are pinned to target geometry that are moving.
In the current setup moving the geometry has no effect on the pinned points as only the frame 1 position and velocity values are read.

Sorry I miss understand :?
I try to update hip file that animating targetP with Geometry “P”.

Thanks,

Is there a way to get groups of points to be pinned? I see how you pinned the one point with the POP Wrangle node, but how would you pin groups of points?
