This project’s source code can be checked out anonymously. You will need a Subversion client. Most systems have one installed by default, for a list of clients look at the link provided near the end of the document.

To checkout bf-blender:

svn checkout https://svn.blender.org/svnroot/bf-blender/trunk/blender You will probably see an error message about the certificate that is not issued by a trusted authority. However the certificate is fully functional and will ensure secure transit of the data. You can permanently accept this certificate.
If you get the message “Certificate verification error: signed using insecure algorithm” without proposing to accept the certificate, open with the file ~/.subversion/servers and add on the bottom of it: ssl-trust-default-ca = no
After accepting the certificate the sources will be checked out for anonymous users.
