Having never used a ColorMatrix in OpenGL or OSG
What effect is this supposed to produce ?
Do you have screen grabs of what it should look like if done in raw Opengl ?

Subject: [osg-users] Problem using osg::ColorMatrix
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 .
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);
// add model to viewer.
