In this one I have changed to adding up all of the impacts rather than the mixing that was going on with the attribute transfer in the last one. It is just a vopsop which loops through the impact points and adds up the deformation. One problem I was having was when I deformed the object, the centre of mass was in the wrong spot. I couldn't figure out a good way to modify that in DOPs... so i ended up moving it in the sop solver, to get it centred again. Another problem was that the object wouldn't be in contact with the ground after it was deformed, so it would end up in mid air with no velocity.. so I added a move attribute in the sop solver, then in DOPs I used a modify data node to move the rbds. The problem with this is that for one step of the sim it would be hanging out in mid air, and then snap to the ground. I ended up just adding the move to P in SOPs after the simulation.... not great because the object isn't solved at that position. At least it doesn't sn...
There is no doubt that Houdini is a most unusual creature, for this is a hamster with an advanced vocabulary and a terribly immodest opinion of his own superior brain power. Houdini believes without question that hamsters are a higher form of life than humans. He is, however, a kindhearted creature (generally speaking) and tolerates the bumbling ways of humans well enough.
