Yes, but there's a if clause that prevents this if the internal format of the TextureChunk is of type GL_DEPTH_COMPONENT (and some others...), see line 980 and following http://www.vrac.iastate.edu/~dkabala/Doc/Code/dev/html/OSGFBOViewport_8cpp-source.html However, as it uses glReadPixels, it should work (glGetTexImage doesn't work with GL_DEPTH_COMPONENT at all...), according to the man page http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/readpixels.html I'll take another look at it tomrrow - I found a way that somehow works (using another fbo viewport with a polygon foreground and a custom made foreground) but it's more a work-around than a solution.
