I looked at adding support for the texture Mapping palette in my OpenFlight exporter, but saw that it is not currently supported in the extant importer. This is, no doubt, why your reflection-mapped Creator models don't render correctly in OSG.
I don't have funding to support the Texture Mapping Palette in the importer, and will need to touch base with my client to see what kind of priority they have for reflection-mapped models. -Paul > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf > Of Garry Keltie > Sent: Wednesday, January 16, 2008 7:24 PM > To: [email protected] > Subject: Re: [osg-users] OpenFlight cow for Christmas > > Hi Gordon, Paul, > > This was a heartening thread as it prompted me to get back > and try yet again to get reflection mapped objects in Creator > appearing that way in OSG. > > I understand the modelling side of multitexturing in Creator > (I hope) but could never see the results in OSG based viewers > when loaded as flt or saved and loaded as osg/ive formats. > The OSGExp project was such a watershed in that department. > > Having a read of the cow.osg sample data I see that there are > consistently missing attributes when exporting from > openflight.
