Velocity from Volume for RBD sim May 23, 2019, 6:40 a.m.

As mkps said you can simply use POP Advect by Volume and there is no need to use sop solver or attribute from volume or etc as using of these nodes speed down your simulation.

This node transfers velocity from volume to rbd pieces per each frame.

Also if you like to have more control over this operation you can do this manually via POP Wrangle DOP or POP VOP DOP.

The thing you just need is Volume Sample Vector node in POP VOP or same function in POP Wrangle.

With this node/function you can grab velocity from Volume according to position of rbd pieces.

Average points on primitives. May 22, 2019, 6:41 a.m.

Hi

What do you mean of average ?!

Average for what ? Position ?
And per what ? Next point ?

However you can do any specific operation per each point via point wrangle sop.

E.g about averaging position, you can get position of next point with point() function and compute average of that position by current point position which is @P.
