Hi all,
I am trying to use OpenFL color matrix functionality through
osg::ColorMatrix but not able to do so. When i apply this to a node
|(cessna.osg) i do not see any effect. I am pasting the code below for
you guys to have a look.
I don't  know what am i doing wrong in this simple piece of code .
cheers RJ

int main(int argc, char** argv)
    osg::MatrixTransform* cessnaMT = new osg::MatrixTransform;

    osg::Node* cessna = osgDB::readNodeFile("cessna.osg");

     // Set color matrix
    osg::ColorMatrix* colorMatrix = new osg::ColorMatrix;
    const osg::Matrix cm (0.15, 0.0, 0.0, 0.0,
                          0.0,  0.3, 0.0, 0.0,
                          0.05, 0.0, 0.0, 0.0,
                          0.0,  0.0, 0.0, 1.0);


             osg::StateAttribute::OVERRIDE | osg::StateAttribute::ON);

    osgViewer::Viewer viewer;

    // add model to viewer.


    return 0;
