051 // Lovely Bubbly

Steps. Add a sphere, then add a cube to the scene, add these two to a boole with the sphere being the first object and the square as the second object, which in hierarchical terms you are saying I wanted to take the cube away from the sphere. Then start with a different set of different size spheres inside a cloner. Small, medium, and large. then set the cloner to object mode then add the Boole object to the cloner object field. this will set up the initial shape, set the distribution to volume. You need to then add dynamics. Add rigid body (apply tag to children and top level or all) to the cloner, so the balls are dynamic objects. then add the collider body (set to static mesh) to the Boole, so that the balls (small medium and large) do not intersect. add plain effector to change the color of the inside, (set the color to custom)add this to the cloner, add a the falloff to the plain effector, a spherical falloff then (change then cloner transform to black), then you need to change the spherical falloff Remap tab, colour to what you like. You can also add cloner with a layer shader to chsnge the colout both inside and out, I added a layer shader to the luminance channel.

Tip: If you want to decrease the number of cloners you have the burst of in the dynamic simulation add a mograph selection tool the cloner choose the clones you want to delete with the paintbrush tool and delete them

Tip: G is to go one frame ahead and shift + F is go to the start of the timeline.
