uint32 bCrumbleSmallestChunks: 1
If set, the smallest chunks may be further broken down, either by fluid crumbles (if a crumble particle system is specified in the NxDestructibleActorDesc), or by simply removing the chunk if no crumble particle system is specified. Note: the "smallest chunks" are normally defined to be the deepest level of the fracture hierarchy. However, they may be taken from higher levels of the hierarchy if NxModuleDestructible::setMaxChunkDepthOffset is called with a non-zero value.
