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
