How to collapse something top-down


Macha

Recommended Posts

I have an object that collapses. At the moment all the components of the object collapse at the same time (RBD point object and a gravity force)

I want it to collapse from the top first, moving downwards.

I thought of using attributes to pass changing gravity values but I can't do that in DOPS.

How would I animate a force along an object in DOPS?

Edit: I think I can do it with a fieldforce DOP, but I have no idea for any functions that give the required forcefield except a simple $TY^2 which isnt animated...

Thanks pal. I see you are putting the pieces into the fracture group and gravity only affectys that group which makes a lot of sense.

All the attribute creating and promoting was done in preparation for the For-Each SOP?

Actually, it
