[osg-users] [osgPlugins] DDS textures not loading on Mac OSX and the latest trunk(3.5.0)

[Robert Osfield]

Hi Curtis,

Thanks for posting the model.   I'm downloading it now.

However it's pretty late here in Scotland, and I have a lot of other
work to prep for the OSG-3.4 release and presentation work to do for
the OSG BOF at Siggraph tomorrow so really don't have time to look
into this evening.  Might have chance tomorrow morning.

I don't have an OSX box to test on, so the only tests I can do are to
look at validity of the DDS files themselves and the code that is
reading them, and the OSG code that is downloading the mipmaps to
OpenGL.  There is chance I might spot something helpful, but suspect
it will be a case of ruling things out and relying upon OSX users to
do specific tests to confirm the cause of the problem.

It would be very helpful if others could pitch in and look into what
might be causing the problem on the OSX.  In particular different
rev's of OSX and different hardware, i.e. Intel vs AMD vs NVidia.  It
may be that certain combinations of drivers and hardware are the root
cause.

Robert.
