Hi Folks,

Has anyone else out there run into this problem:

I am generating an .osga database using OSGDEM.  The imagery has four
components (Red, Green, Blue, Alpha) but my database is black wherever
the alpha is < 1.0.  What would cause this?  Is it texture compression,
which I hope isn't being used?

When I use a shader to just show the alpha layer, it's all white.
Showing just one of the color layers shows that they are black where the
imagery has alphas of < 0.0.

When I use the same imagery to build a database in OSG 1.0 I get the
alpha values, but loading that database into an application I have built
against CVS OSG, I get the same black behavior.  Strange.  Any ideas?
