yes, but you must have the OpenFlight loader revision R15.4d or newer.

yes. the feature object includes the FID and SMC fields from the OpenFlight
face and/or light point attributes. you must enable this loader mode in order
for this data to be attached to the geostates and/or lpstates. the result will
be state objects that are uniquely separable by FID and SMC.

no ... fltFeature

>user data ?

yes. however, note that this is a loader extension to the geostate.

Regards.
