Hi Robert,

Maybe I spoke too soon...  Just to add some more data
to this thread:

The attached file, terrain.ive is something we use for testing
and is also delivered with Sundog's Triton package as part
of a demo.

This file loads fine on Linux all versions of OSG.

On the mac it loads fine on OSG 3.3.1, but since then
no textures are loaded with this file.

I also have another set of openflight files that have the
same issue, Linux all versions is OK, Mac OS, nothing
after 3.3.1 will load the dds textures.

This link to a small sample database, also has issues
on the Mac, but works fine on all Linux versions:


It is still likely that this is some Mac OSX OpenGL thing, but
if some time comes up might be worth looking at just to 
be sure what is happening with them.  Maybe its an old
version of flight formatting or something.

Loading one of the flt tiles on the mac, the only suspicious 
message I see is:

Warning: Detected OpenGL error 'invalid operation' at After Render::compile

OpenGL extension'' is not supported.


Thank you!
