uhm, your description suggests you are doing the right thing, passing a
MField to setUniformParameter is the way to pass arrays.
What exactly is not working? Do you get a compiler error, an error from
the driver when it compiles the shader, do you get incorrect values in
the uniform? Also, what version of OpenSG is this with and on which
platform?
Cheers,
Carsten
