Hi Eric, The OSG automatically reference counts objects, so when you do the setTexture..(0, txt2) the tx1 will be unref'd automatically and if no other references exist it'll delete - which is correct. Your tx1 pointer is now a dangling pointer and when you assign to the stateset it of course crashes.
The simple solution is the use ref_ptr<osg::Texture> instead of the C pointer. Robert.
