I have several objects that I wish to simply drop as one sole body. So far reactor will act upon all the individual objects, but the out come is that they all separate and run off in many directions. I wish to keep them attached and fall while still connected. Constraints should do the trick but I think I have the wrong order

Constraints to the objects >> Constraint solver >> RBcollection ??

I get errors that the either one or the other is no longer in the RB collection.

	Attachment

did you need them to stay together at all times?

You can use groups with reactor to hold things together (see compound rigid body in the help file).

If you need the parts to break apart when they hit something, then Fracture might work.

Thanks!

My error was that I had a previous hidden RB collection which I had already used for the other members and with the two it was giving me the errors.

Onward errr.... Downward
