Hi All,
I'm investigating the NVidia Uniform array issue, there have been some
suggested changes that address these but only copy and pasted into
emails. Could you send me the complete modified files so I can review
them as this will avoid any possible ambiguities.
Cheers,
Robert.

FYI, I just tested the new NVIDIA beta driver 280.19. Same problem as with
275 series.

Hi, John For me it works on new drivers if i append "[0]" to uniform array name, BUT it wont work on old driver anymore with this change. So for now in our apps we have to use two uniforms for each uniform array, one original and another with "[0]" appended so stuff actually works on both old and
I worked around this issue with an ArrayUniform helper class. The code is

Thanks, I followed the suggestion from Michael Platings (
http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg46081.html)
to
add the lines
for (GLsizei j = 0; j maxLen name[j]; ++j)
{
if (!isalnum(name[j]) name[j] != '_')
{
name[j] = '\0';
break;
}
}

It won't because it seems that internally OSG changes:
Color
...to...
Color[0]
...even, on non-array
I posted some comments on this issue as well:
http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg46003.html
My point was that the spec implies that BOTH naming methods are legal, and
thus OSG should support them both IMHO.

(Doesn't matter what OS, the bug is on Linux and Windows for me...)
It appears that this driver doesn't understand GLSL arrays anymore. At
least, not like it used to.
It's not just you.
I tested on a Quadro 4000, driver 275.36, Windows 7 64-bit and it does not
work for me either.
I also tried on a GeForce 8800, driver 270.61, Windows XP and it worked
correctly.
Cheers,

Not quite sure why NVIDIA released them , as they should have failed the QA
