[osg-users] osg 3.3.8 and SAMPLER_2D uniforms

[Robert Osfield]

Hi Nick,

I don't recall an specific changes relating to Uniforms between 3.3.7
and 3.3.8.  Perhaps it's just an error elsewhere that shows itself in
different ways on different systems, perhaps an uninitialized variable
or a shader that isn't valid GLSL but different compilers are doing
different things with it.

Without an example illustrating the problem there isn't anything more I can do.

Robert.

Robert.
