hi OpenSG users,
i am trying to make a little order in my application
(the code is getting a bit confused, in time).
One thing i noticed is that i am still reducing my 
textures from 16 bit to 8 offline. This was due the 
fact that when i first wrote the app, OpenSG still did
not support the 16 float format.
Now i'd like to load the textures in their native format
and then process them during the rendering cycle via 
some appropriate GLSL shaders. 
My problem in: the skybox does not seem to use any
geo node, so i can't see how can i attach a shader 
to it... It would be pointless to have half the app 
loaded with 16 bit textures and the other half using
the old code... 
any clue?

thanks as usual, enrico
