tricecold Posted June 15, 2014 Share Posted June 15, 2014 Hi all, I am trying to figure out a case. I have four boxes as RBD packed objects, they need to act like thrusters spring constrained to an object in the middle, they need to keep the middle object in balance floating I can keep the object floating by giving it rules in a sopsolver, but I cannot find the correct way to isolate and give different velocities to thrusters depending on their individual position. Like if thruster 1 is lower than center point of the board apply thrust to those points only. So I tried to isolate thrusters by creating attributes for thruster points, I tried to group them, but I cannot see this inside the SOP SOLVER in the DOPSOLVER. I am sorry I cannot share the scene file, but basically I am trying to create a self balancing and floating object with 4 thruster on sides, but please dont send me a finished scene. I just need the tips. Quote Link to comment Share on other sites More sharing options...
tricecold Posted June 15, 2014 Author Share Posted June 15, 2014 I figured a way, I can create the groups after the packing is done, this works, but I have only 4 objects so for this scenario its managable, but usually there are hundrreds of objects to deal with sometimes thousands. I usually prepare all the objects with all the attributes I will need then I create the packed Rigid Body, so It feels like I am still missing something.

anim Posted June 20, 2014 Share Posted June 20, 2014 each point in SOP Solver representing Packed Primitive RBD contains a name attribute you can use to filter just your truster objects or any objects you need by pattern or any other means Quote Link to comment Share on other sites More sharing options...
