Hi guys!   I have a scene where I want to control an attribute at sop level to control a pop wind inside dops. Here there's a description of my setup: First, I am using an attribute transfer to set my attribute called "popforce" to my packed geo from 0 to 1 over time. after that, in a dop network I am using a wind pop force in conjunction with a bullet solver and a multisolver. In the rbd object I have activated the option "create deforming active object" to transfer the attribute inside the dop net, so far so good, now I can see my attribute getting changed in the "Geometry" inside dops.  At this point I thought I could use an point expression inside the activation field of my pop wind in this way (the attribute name is "popforce") : `point("../rbdpackedobject1/geometry/",$PT,"popforce",0)`  But it's not working is there any typo or am I doing something wrong?   Thank you!     popforce+bullet.hipnc
