Gummi Ball uses same technique like Jello. It is one Lagoa simulation with two different emitters to perform the collision between these sphere shape jello clusters. But the meshing is now changed. Instead to create a very big ICE tree to divide all the balls into separate meshes, i use the brand new feature GroupID in emPolygonizer. This feature meshes groups of particles as one separate mesh each group. I use the current frame number as groupID. In this case that worked well, because the particles for one ball created in one frame.
The motion blur comes from emReader, the old Geometry Reader from emTopolizer could not handle Motion Blur for Redshift very well ... but emReader did a good job here.
