DEFORMING RBDS STICK TO
ANIMATED MESH

Gotta jump on the motion graphics trends you know

HOW TO

Reading this cgwiki post on RBDs I wanted to have a go at doing something similar. This setup uses constraints instead to allow deforming RBDs to stick on a surface. 

In short, I scatter a bunch of objects on the geo. Make a constraint for each point between the rest position(first frame) and the animated mesh. When using a hard constraint this makes the objects stick to the mesh while at the same time allows them to be deforming, in this case scaling up. A spring constraint gives a more playful look which is quite nice too.
