Hi Robert, I looked over the OverlayNode implementation and recognized that it seems that a shader is missing at line 1094 in OverlayNode.cpp (latest SVN version), when the overlay perspective vertex shader can't be found at "shaders/overlay_perspective_main.vert". At all other shaders there i

Hi David, The OSG uses ref_ptr<> that should ensure that no memory leaks occur, but.. this does seem assume they your own application is using them - if you code fragment it does which is good practice. Another possibility w.r.t memory leaks is a false positive - VS's memory tracking tool is bug
