We have a model of an human internal organ, made up of a series of triangle meshes. The are between four and seven sets of meshes combined into an an assembly. During a long ( multiple hours ) automated test, where a surgical instrument is moved through the scene repeatedly ( Made from implicit function sources and also combined into an assembly) , there is an issue - and the best way for me to describe it is that the assemblies " come apart. Each actor in the assembly is moved to a deferent place in the scene, as if perhaps they " exploded ".
