COLLADA 1.4.1 is an update to the COLLADA 1.4.0 XML Schema namespace. The update fixes issues reported by users without adding new features and is backward compatible with the existing 1.4.0 schema. COLLADA 1.4.0 documents will validate against the new schema. The COLLADA specification has been enhanced with more examples and clarifications about existing features. A new release notes document supplements the specification with additional information about effects bindings for material instancing, texture mapping, rigid constraints, transparency, and skinning calculations.
