Hi ?,
as Robert suggested, print out some values of the matrices to make sure
that they are valid and that the multiplication order you are using is
correct.
OSG has functions for printing matrix values to screen, see / search for
<osg/io_utils>.

G'Day. I have some questions about osg.
There is function MatrixTransform for reseting position/rotation/scale.
[code]
osg::Matrix mat;
if (!position) mat.preMult
(osg::Matrix::translate(MyTransformMatrix->getMatrix().getTrans()));
if (!rotate) mat.preMult
(osg::Matrix::rotate(MyTransformMatrix->getMatrix().getRotate()));
if (!scale) mat.preMult
(osg::Matrix::scale(MyTransformMatrix->getMatrix().getScale()));
MyTransformMatrix->setMatrix (mat);
[/code]
When call this function often ,time by time objects disappeare from the screen
and OpenGL writes many errors. Whyt can this happens?
OSG 2.6.x, 2.7.x; MS VS2009
