The state has links between views '<CameraLink name=' which somehow cause rendering of everything when I touch a view and the view image I want to write is almost never the right one. I removed these links and now everything works fine. Thank you for your help!</div><div><br></div>Ps. The python script is that I've posted above (just with two hardcoded pathes 'pvsm_file' and '<span style="font-size:12.8px">baseline_path'). The pvsm state won't be reproducible with paraview since it uses many custom plugins.</span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">2017-07-03 12:44 GMT-04:00 Utkarsh Ayachit <span dir="ltr"><<a href="mailto:utkarsh.ayachit@kitware.com" target="_blank">utkarsh.ayachit@kitware.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Mind sending me the script?
