Everything in the scene must be in a hierachy which links to one root, if not a scene root will be added eg
- represents a link
example1
head-neck-torso-pelvis would not need a sceneroot as everything links to pelvis in the hierachy.
example
walla-ground
wallb-0;no parent
wallc-wallb
when this is exported a scene root needs to be added as their will be two groups of entites without a common parent
so it would endup being
walla-ground-sceneroot
wallc-wallb-sceneroot
ps not to good at explaining but i hope it helps.
