Thank you for the your reply.<br>
<br>
I've tried adding dirty() and it still doesn't work.<br>
<br>
Code:<br>
<br>
virtual void operator()(osg::Node*, osg::NodeVisitor* nv)<br>
{<br>
        if (nv->getFrameStamp())<br>
        {       <br>
                _coord = dynamic_cast<osg::Vec2Array*>(_geom->getTexCoordArray(0));<br>
<br>
                if (_coord)<br>
                {<br>
                        for (unsigned int u = 0; u < _coord->size(); u++)<br>
                        {<br>
                                _coord->at(u).x() += 0.01f;<br>
                                _coord->at(u).y() += 0.01f;<br>
                                _coord->dirty();<br>
                                _geom->dirtyDisplayList();<br>
                        }<br>
                }<br>
        }<br>
}<br>
<br>
<br>
<br>
What should I do more?<br>
<br>
