// This is required for curves in saved scenes, as its parameter data is not part of the parent asset's
// parameter preset. Also the _geoID and parameters._nodeID could be different so uploading the
// parameter values before cooking would not be valid for those IDs. This waits until after cooking
// to then upload and cook just the curve.
// Admittedly this is a temporary solution until a proper workaround is in place. Ideally for an asset reload
// the object node and geo node names can be used to match up the IDs and then parameter upload can happen
// before cooking.
