AnimationSet {

 Animation {

  AnimationKey {
   4; #DWORD keyType;
   2; #DWORD nKeys;
   # array TimedFloatKeys keys[nKeys];

  { Scene_Root }

For the  { Scene_Root }  node, the reference manual doesn't mention about

this node. What does this node refer to?


From the doc,

Contains animations referencing a previous frame. It should contain one reference to a frame and at least one set of AnimationKey templates. It also can contain an AnimationOptions data object.


Why does animations refer to a previous frame?

Ps: legacy depends on your goals in my opinion (exporters are still fine, including binormals/ tangents and multi textures). On the other hand the exporters for example for max, might not deliver 100% of what you need.
