[osg-users] OS X (10.9) Texture2D with hardware compression results in no texture data.

[Robert Osfield]

HI Nikolay,

The OSG's detection of glTexStorage2D is currently based on checking
whether the function pointer is available in the driver, if it's available
the OSG assumes it can be used.  So perhaps the driver has the function but
doesn't actually support it on the hardware you are using.  Coulld you post
the output to glewinfo?

Could you try setting the env var OSG_GL_TEXTURE_STORAGE to OFF to tell the
OSG to override the enabling of glTexStorage2D.

Robert.
