DonRomano Posted July 26, 2019 Share Posted July 26, 2019 Hey guys, I'm working on a rbd simulation and I can't figure out how to apply a force I've created in a Vop to only one rbd object. I want it to affect only my buidling structure and not the windows. I tried with $OBJID, creating groups, but it doesn't want to work , I miss where I'm wrong...

woodenduck Posted July 26, 2019 Share Posted July 26, 2019 Create a point group on the rbd_building geometry at sop level right before it goes to the dopnet. Add that group name to your Force geometry vop. Quote Link to comment Share on other sites More sharing options...

I already tried but what is weird is that, when I apply the force to a group, the force loose some power and dosen't behave the same way when I apply it to all the groups, I don't know what is going on here...

Atom Posted July 27, 2019 Share Posted July 27, 2019 The force to a group may be working, but the members of that group might still be bound by constraints to members that are not in the group. If you have constraints to the windows, that could be it. Try turning the windows into a static collision object, instead...? Quote Link to comment Share on other sites More sharing options...
