Properties

Property	Type	Description
index	integer	The index in the node array. May be different than material, geometry and attribute resource id. See mesh for more information.
parentIndex	integer	The index of the parent node in the node array.
lodThreshold	number	When to switch LoD. See nodepages[i].lodSelectionMetricType for more information.
obb	obb	Oriented bounding box for this node.
children	integer[]	index of the children nodes indices.
mesh	mesh	The mesh for this node. WARNING: only SINGLE mesh is supported at version 1.7 (i.e. length must be 0 or 1).

Note: properties in bold are required
