I am trying to crumble a block like in the gif below. Is there a way to have particles act like bullets and crumble the block? - Here I have just animated some spheres to try and do the same thing.
I have only been able to make the particles bounce off surfaces but the actual rigid body object's are never affected. i.e they stay put.
I am using cell fracture and bullet constraints for the block in the top image.
If it's not possible then is there a way to have a block 'crumble' away using forces rather than particles?
