UNCLASSIFIED Thanks again Paul, I am using ref_ptrs but maybe not properly.
I will analyse my code again. Cheers Russell IMPORTANT: This email remains the property of the Department of Defence and is subject to the jurisdiction of section 70 of the Crimes Act 1914.

Furthermore, I now make all modifications to the scene tree in the render thread (prerender) but I still get the occasional crash in the render thread: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\vector line 116 Expression("this->_Has_Container()", 0) Unfortunately the error doesn't occur reliably enough to track down. It does seem to occur when I modify the scene tree.

I can't remember the actual call. good luck, On 09/11/17 14:49, Thamm, Russell wrote: UNCLASSIFIED Hi I am in the process of porting an MFC application from plib to osg. Currently, if I want to actually modify the scene graph (adding, deleting nodes etc) while the render thread is running I do the following: parentNode->setNodeMask(0); modify scene graph below parent node parentNode->setNodeMask(~0); This seems to work but is there a better way?
