[osg-users] Effecting MatrixTransform matrix change

[OpenSceneGraph Users]

Hello everyone! This must be a simple one... I have a node that has one 
parent which is a MatrixTransform. I simply need to move the child node to 
a specific location that is computed at run time. I figured I just needed 
to do the following, but this caused no change in the location of the node:

const osg::Matrix OriginalParentMatrix = 
pParentMatrixTransform->getMatrix();

osg::Matrix TranslateContribution;
TranslateContribution.makeTranslate(10.0f, 0.0f, 0.0f);

const osg::Matrix FinalNewMatrix = (OriginalParentMatrix * 
TranslateContribution);

pParentMatrixTransform->setMatrix(FinalNewMatrix);

No matter what translation I set in makeTranslate(), the child node doesn't 
move. Is there some call I'm missing to cause the new matrix to take effect 
on the node's parent matrix transform? Thank you in advance!
