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 is a fallback shader implementation as a char[] when the shader file can't be found. Thanks, Daniel _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
