BULLET PHYSICS + LW INSTANCER + OPEN VDB NODE TREE

The following example shows Bullet Physics in combination with LightWave Instancer and open VDB. For this, various "cells" of different sizes are "locked" between two negative forcefields which have a collision detection so that these "cells" are repelled from each other in the stretched gravitational field, but are held together by the gravitational field. a very large "cell" is then animated through the "cell cluster" and this large cell displaces all the cells in the cell cluster. because the cells are trapped by the gravitational field, they can only escape within the gravitational field when the large cell hits them. so the cells escape only along the "forcefield" and then rearrange themselves. The cells are then covered with the lightwave instancer with further smaller cells to create more structure. finally, the cell clusters animated with bullet physics are then linked with "mesh to volume" in open vdb. in open vdb, the dilate function is then used to set an individual distance of the "liquid" that covers the cells for the different cell groups, so that the "liquid" behaves individually depending on the size of the cell (in terms of its distance from the cell surface). to create further finer structure, you can then use the instancer id to instantiate the smaller cells on the cells with the gradient 2 node (Octane PBR) with different colors.
